Firefox Community Forum

I have been unable to log into my email provider from their home page https://mailbox.org/en/ using Firefox. There is a progressive web app that "goes with" Firefox (if that is the right term) and that does not seem to work either. I get blank screens. I have succeeded in logging into mailbox.org in Microsoft Edge and in Brave. Can you please give me any clues as to what settings or whatever I need to configure in Firefox to be able to log into mailbox.org ?

Please help me to open Thunderbird. All of my critical communication is there. Ecentral.com is my email. Thunderbird has not responded since a Windows update on 01/20/26. Should I uninstall that update?

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...

I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2

When I try to download a statement from my bank I just get a blank page pop up. This used to work with Firefox and it works OK with Chrome. What has changed ...or is there a Firefox setting that is wrong?

Recently i added some bookmarks in a dedicated folder. Afterwards i don't see the bookmark in that folder. Hoever if i click on "Search bookmarks" and enter its name the bookmark is listed. If i then rightclick on it and select "Show in folder", the bookmark is shown in the correct folder. What is wrong ? Thanks

FF 147.0.1 (64-bit) Linux mint 22.3

Hi everyone, for some time (~2weeks) I have the issue that I don't get any autofill-information in login screens.

I checked the relevant settings/passwords/"Fill usernames and passwords automatically" (OK) I deleted my ff profile and reinstalled ff. (whereas here it worded briefly) I disabled all plugins (only have "uBlock Origin" running at the moment)

I'm pretty puzzled, does anyone have any ideas? Best, Stefan

Hi, I’m facing an issue with Mozilla Firefox where some websites load very slowly, and sometimes pages don’t open completely or show loading forever.

I’ve already tried restarting the browser and checking my internet connection, but the problem still happens randomly. Other browsers seem to work fine on the same network.

Can anyone guide me on what could be causing this issue? Are there any Firefox settings, cache options, or add-ons I should check to fix this problem?

Thanks in advance.

The 29. january I got no sound when streeming video from Firefox. I checked the situation with VLC, another media player, which had no problems with the sound. I opened Windows "sound control settings" and chose to send the sound to the monitor (HDMI). Then I got sound from Firefox. When I sent the sound back to the original device, which is an USB Audio DAC, because I use an external amplifier, and my PC doesn't have the SP/DIF output. Again there were no sound from Firefox, but sound from VLC. In addition I started Microsoft Edge, and got sound! Which means that the problem is only with Firefox.

Then I checked the time for the last Firefox update. It was january 28, the day before (or it could have been the same day), and the new version was: 147.0.2. That made me beleive that the cause of the problem was the software update. What else could have caused this problem ?

I do not know how to fix this problem. I need help, otherwise I have to quit using Firefox, which I have been using for a decade without any problems. I am using Windows 11.

I'm running Firefox 147.0.2 on a 2020 MacBook M1, with Tahoe 26.2, and appear to have 2 versions of 'identical' Firefox on my machine. Applications shows only 1, but there are 2 distinceticons on my Tool Bar. I'd like to delete one of them, but can't do it successfully. Any help appreciated!

The browser is very slow when opening a new tab... When I've opened Youtube it says that the Page is slowing down the browser and it takes a very long time to respond... I'm using MacOs Monterey 12.7.6 and I believe my Firefox is up to date
