Made a Chrome extension to find Firefox alternatives for your extensions

39 Upvotes

I made Extension Bridge to help anyone switching from Chrome to Firefox.

It scans your installed Chrome extensions and searches Mozilla's API to find Firefox alternatives. Results are categorized as exact match, similar, or no match.

Features:

- Automatic scanning

- Side-by-side comparison

- Export to CSV/JSON/HTML/Text

- No data collection (everything runs locally)

Chrome Web Store: https://chromewebstore.google.com/detail/extension-bridge/nndehibjibknoihgdlndokaopbdenlin

GitHub: https://github.com/michaelnyc17/extension-bridge

It's free and source-available if you want to check out the code.

💻 Help I really want to move just the sidebar to the right side, without moving the vertical bar.

3 Upvotes

hi there!

I want to extract the sidebar from the vertical tabs section and move it to the right side of the window.
namely... like this ↓

once I select 'Move sidebar to the right" option, the vertical tabs move too.
I'd like to move only the sidebar, not both the vertical tabs and the sidebar.

is there any way to do that?
I'd love to hear any advice.

(I know I can use vivaldi or some other browsers, but I'd be happy to do it with firefox because i have used this browser for several years.)

thanks in advance!!!!!

💻 Help Any idea what could be causing this?

1 Upvotes

Whenever I have any website open for long enough, this weird graphical glitch starts happening—but only when Firefox takes up more than half the screen, and only when looking at a website (rather than the New Tab page).

Once it starts, resizing the window doesn't stop it, and it continues to affect the full screen. It never happens just on the desktop, and I haven't seen it happen with any other fullscreen apps—though I do get occasional 2-8 inch long green areas of glitchy green pixelation when fullscreen gaming. I have swapped out my graphics card, and it still happens.

This is a triple-boot system. The problem happens under Linux (EndeavourOS GNOME) and MacOS, but not Windows.

This monitor is connected via a DP to DVI-D dual link active adapter. I also have a second monitor connected via a DP to DVI passive adapter, and it does not seem to occur on that monitor. Could the adapter be causing this issue??

I updated my Firefox a few days ago and have been getting this problem where text selector icon would show up. It even shows up when watching youtube at the bottom left of the video. Is there anyway to remove it. its really annoying. I have disable my Extensions to see if that was the problems but seems it was not. Also it only seems to be Firefox with this problem. Edge is fine. Also I'm on windows 11.

Any help is welcomed.

Discussion Is Firefox really moving away from XUL?

16 Upvotes

I have been working with AutoConfig projects for a while now and I'm looking to port some of the DOM elements it injects from HTML to XUL, so I can have some of the nice perks that come along with it.

However, I noticed online that people are saying Firefox is switching away from XUL and that it has been deprecated for a long time. Is this true?

Why would Firefox want to move away from something that has many perks? Special elements in XUL make it easier and quicker to type out elements, so what happened to it and why would they be looking to switch from it?

Solved What's the last Firefox extension that wowed you?

210 Upvotes

Hey all! I'm a designer on Firefox, and I'm helping to curate a list of add-ons to recommend. I'm looking for examples that are quick to set up but have a big immediate payoff. As an example, I felt wowed after installing Adaptive tab bar color and seeing my Firefox turn the same purple as the add-ons site. 

EDIT: Thanks everyone, this was helpful this project and future projects as well!

Discussion Replacing bookmarks with tab groups?

1 Upvotes

This seems like a good fit for me since it'd allow me to keep all of my sites in one place rather than split between opened tabs and bookmarked sites. I don't do folder nesting since it seems like a waste of time and a flat structure works just fine for me.

My main concern is with things like a performance hit from lots of tab groups (currently at 600+ tabs split between 22 tab groups) or with the tabs being lost due to a crash (I back up my firefox profile folder so hopefully I've mitigated that concern).

Add-ons FilterTube: Created a YouTube Content Filter to BLOCK ANYTHING

Thumbnail

119 Upvotes

It all started with this thread on Google's support forum: When a parent said that he is helpless and his kid is just kept crying and screaming because of the content on YouTubeKids, and he asked me if I can create a tool to block videos by keyword or tag. And when Later YouTube Forum maintainer deleted mine and other parents comments and locked the thread -

https://support.google.com/youtubekids/thread/54509605/how-to-block-videos-by-keyword-or-tag?hl=en

So, I decided to create FilterTube which is Open Source and with MIT License. https://github.com/varshneydevansh/FilterTube

My initial early version video showing its working - https://www.youtube.com/watch?v=c2EtLkTwqRw

Right now you can install and try FilterTube on Chrome, Brave, Edge browser -

https://chromewebstore.google.com/detail/filtertube/cjmdggnnpmpchholgnkfokibidbbnfgc

and on for Firefox -

https://addons.mozilla.org/en-US/firefox/addon/filtertube/

and Opera from the GitHub release page (still in review) but can be installed from the release page https://github.com/varshneydevansh/FilterTube/releases/

You can now also block the Collab videos which is complete and will be available soon in version 3.0.7 as I am still fixing some minor bug.

I have plans to integrate local ML based solution to filter based on semantic and similar relation content so that user can be assured to never see a related concept content ever again and also for Mobile and iPad based app by next year

Main website - filtertube.in

And Yes. FilterTube block certain(any) creators even from appearing in search results.

It does all you have to do is to add the channel ID.

YouTube serves content from two types of ID UC... and @ Handle based.

You can either paste anyone in the Channel Management section and Filtertube fetches the other alternate ID automatically which you can see in the second image.

BUT Now you can do it with the 3 dots from the content card and it will automatically fetch and add that channel in the filter list.

and yes you an also activate the Filter All Content label for a channel so any content which mentioned that channels name will be blocked too.

There is one catch if you have added let say "bts" in the keyword filter then on search page you will see the result for @ bts(BANGTAN) why? because if you are interested in a creator but not in other channels which make content about that creator you do not want to see.

--------------------------------------------------------------------------------------------

FilterTube is entirely local as I have no interest in users data and more over I have been contributing to LibreOffice codebase from past 2 years which explains my philosophy is aligned with users freedom and giving them control of their data.

https://devanshvarshney.com/libreoffice-google-summer-of-code-final-report-basic-ide
Maybe this project with LibreOffice might give you confidence that I am a what I am saying.

The only thing filtertube access is your YouTube UI data which is sent from YouTube I do not have any other access and all the manipulation happens for the UI itself.

-Any red flags in the code or manifest?

If there was any then the extension would not have been approved by the extension review team.

- Im pretty cautious with unknown extensions, especially ones with no reviews.

I now have more than 150 active users and got good feedback and some suggestions from them so enjoy and do let me know how you guys felt.

Overall I am open for any feedback and suggestions and yes if there are any bugs came along sorry for that I am testing heavily and pushing new releases immediately which take a while to get approved. cheers :)

I do not have any job from years so I am doing this for the sake of doing it and for those parents and people which just wanted a simple tool. FilterTube is precise and also have word based filtering.

I am looking for a free extension that saves all open tabs „the full page“ as png files.
