Firefox Support Forum

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

For some time now, e-mails have been arriving with a delay, e.g. from April 15, they arrived only on April 18. The mail is on the home.pl server pinned via IMAP.

Hello,

I added a browser extension Search by Image by Armin Sebastian some time ago and it worked just fine till recently. Now, every time I need to find some image I get the page with cute creature sitting and fishing in bucket of water with info stated: "Your search did not match any documents. Suggestions: Try different keywords." (screenshot attached). It happens every time, no matter what kind of image I'm looking for. I also added another extension Search by Image on Google by Gustavo Silva and it's the same issue.

Would really appreciate any help with it.

Thanks,

Magdalena

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

I've been using Firefox home content shortcuts usefully on my Windows system. I installed Ubuntu on Vmware last night and synced Firefox account in it. After that, the home content shortcuts are all changed to the default status. I think it's because that I clicked the sync now button on Ubuntu. Is there a way to roll it back? Thanks.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

Hi,

We have an application where we do not want to share the session cookies between tabs. Is this possible? If above answer is yes, next we would like to filter out some cookies by name that should not be shared across tabs. Meaning, we want some cookies that can be shared across tabs and some should not be shared.

Thanks in advance

Hi Everyone!

I'm wondering if anyone can shed light on this.... I'm using the very latest version of Firefox 124.0.2 (64bit) And recently having a problem when video chatting on facebook when chatting I can't see the "Cam" Icon to call up. Yet on Crome all is good.

Any help?

When I turn off the windows animations in Windows 10 the font on Twitter.com changes somewhat. I believe it is altering the character spacing/scaling.

I have not had this behavior on other browsers (Brave, Edge, Chrome & OperaGX tested). I have not noticed this on other websites, but I also haven't really looked.

Windows version 22H2 (OS Build 19045.4291) Firefox version 124.0.2

Images provided are with them off, then on

Steps to recreate 1. Load a tweet (tweet in the images: https://twitter.com/FedeItaliano76/status/1779855670432408011) 2. Turn off window animations (settings->display->show animations in windows->Off) 3. Reload the Tweet

This is not a critical issue for me, but I think it's worth mentioning

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

In previous versions of FFx, toggling to Reader view used the same font I'd chosen in Settings / wherever. Now it's something else, in boldface with no distinctions made in original view (italics, not italics, etc). & there doesn't seem to be any way I can control fonts in Reader.

Any suggestions? In plain English, please, I am NOT a programmer or computer professional, just a regular human trying to use this new version that seems to have broken everything I liked about FFx.
