Hello,

After installing Firefox (103.0.2) on a clean install of Manjaro (21.3.7) Gnome (42.4), I started noticing that mouse hover effects such as highlighted tabs, UI of a video-player appearing etc. are delayed after my PC exits hibernation (I am not sure if that is the only cause and if that really IS the cause). Weirdly enough the select menu I used to answer the "Which topic best describes your question?" question to create this post experiences no delay in highlighting the hovered element. Relaunching Firefox fixes this issue temporarily.

To be clear this is no performance issue since everything except mouse hover related interactions are fluid.

Thanks for helping out

Whenever I use Firefox 109.0 (on Ubuntu 22.04) to transfer money between savings and checking in my online banking account, I get a window pop-up that says "No Apps Available". This is something going on my bank's servers and shouldn't require Firefox or any local helper apps on my end to do anything. I will post the window that pops up. Has anyone else encountered this? And is there a way to disable these pop-up?

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

We have lost our developer access to manage an extension. Nobody knows which email address and account was used to manage the extension.

What is the procedure to get ownership of the extension ?

Thanks Frédéric Jahard

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

i am using Firefox Snap version 103.0.2 (64-bit) on Ubuntu 22.04. Whenever I try logging in to twitter, It shows a blank screen after I press login button after entering the password (Image is attached). I can login to other browsers I have installed on my laptop.

I have tried removing cookies of Twitter.com several times and even reinstalled snap version but the issue is still there. Any fixes for this? I can't keep switching browsers just for using twitter.

The issue appeared about two days ago. On the page https://index.hu/ the left click is not working from firefox. This is the most popular news site in Hungary. I also experienced the issue on other sites.

It is working fine from chrome and chromium. The issue is appeared on linux and windows 10 machines as well.

I tried to clear the cache but it does not help.

Please fix this ASAP or I have to delete your browser.

My firefox suddenly became very slow after an update. On each web page I have to wait maybe 10s, and nothing happens, and after that all is ok (really fast). Safe-mode didn't help. Thanks, Piero

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

Related to some personal SVG project files. Which are relative large files (containing lots of generated paths and other data).

On the largest of these files I spotted that some general svg-viewer failed with a "XML parse error: cannot load more than 200.000 XML elements" error message.

The same file, when viewed in Firefox (114~, Linux, Mint), also developed some odd hiccup that did not make sense. Unless ...

Is there a similar limitation active in Firefox ?

- I tried to see if "Inspect>Console" gave some potential related message on this. But spotted nothing out of the ordinary. - Searched developer.mozilla.org for any related svg data. But could not find any. - After ditching some data in the effected file, unrelated to the hiccup part, the hiccup disappeared. Suggesting I did hit some svg limit in Firefox. - File size: ~26.5MB. Number of elements: Other than more than 200.000, unknown at this point. (not sure how to count them at this moment either)

Hi everyone,

I've installed Debian 12 with Firefox 102.12.0esr (64-bit) from scratch instead of Debian 11. Just after it I noticed that all add-ons I used for a long time do not work anymore.

When I go to Menu > Add-ons and themes, I see all add-ons enabled. However, all of them do not work, and they even do not display their icons on the Firefox toolbar as they did before.

A couple of examples of add-ons that do not work: - Enhancer for YouTube - ImTranslator: Translator, Dictionary, TTS

I run Firefox via Firejail sandbox (like I did for years without any problems). All add-ons and settings came to my new system via Firefox sync. I tried to run Firefox directly (without Firejail) and nothing changed, add-ons still do not work. Also, I logged out of my Firefox sync account and reinstalled add-ons on Firefox running directly (without Firejail) and it did not help.

Appreciate your help - how can I enable add-ons in Firefox?

Hi,

I have Firefox 102 ESR in Debian 11 (LXC in Chrome OS). It is the en_US version with Czech spell checking dictionary installed as an add-on. I can switch the spell checker from English to Czech in ordinary text areas by accessing the context menu via a right mouse click.

However, I'm using a proprietary e-commerce system (Shoptet) with a WYSIWIG editor that has its own context menu, overriding the default one in the browser. I can't switch the language for that reason. Is there a way to switch the spell checker language for a particular text area without access to the context menu? Thank you very much.

Petr

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.
