Forum zgromaźeństwa Firefox

Today randomly i noticed that my bookmark bar is waaay shorter out of the blue, i didn't change or adjust anything, all i do is the updates from mozilla that's all, it was all music it really saddens me because atm it's lost forever, i hope somebody can help me (i don't know since when it disappered i literally just noticed it right now ...)

idk when exactly this nonsense happen or with which update but thats outrageous.

why the hell it canceled in my setting the check mark at startup for opening previous tabs?! i haven't touched the settings in ages since i set them up so it had to be one of your stupid updates.

fortunatly chatgpt had a solution to bring all my tabs back otherwise i'd fucking rage out.

i'v been using firefox for ages but after this i was really thinking i should switch to something else.

I have the newest firebox version and i have you tube connected to the menu bar and 2 icons for it on the desktop i m not sure what if an addon are cause it to stay in full screen screen mode i do not wan it in full scene mode. i have done everything i know how to do to stop it from full screen please how do i get it ti default always just giving you a sample of what Iam getting just a sample of the size i do not have firefox zoomed it is on 100 percent and not zoomed the sixes is 16 and 14 an no larger.

I was reinstalling windows because there was alot of unwanted cache in the c-drive and I thought that the passwords would be saved on my google account but i didn't know they were saved in the browser. Is there anyway that you could help me to recover those passwords i can provide you any needed information if it helps in recovering those passwords. Thank you

starting at the update before the most recent one (currently june 30 2025) my firefox browser on my windows 10 pc simply doe not work at all. i am surprised it actually loaded the support page allowing me to write this, but every other page i try to open gets stuck in infinite loading. next thing i am going to try is uninstalling/reinstalling I GUESS. firefox on my other PC and phone are totally fine. is this bc i am running windows 10? please help :C i installed chrome and its absolutely awful

When signing in to online Shaw Webmail, message says 'Security Check Failed. Clear your browser cache and retry'. Screenshot attached. Have done so in "Clear browsing and data history", (as per Firefox guidelines) multiple times, for all History and cache. Did not resolve issue. Contacted Shaw Support; they instructed to try logging in with Chrome browser. Worked fine. Issue appears to be strictly with Firefox Browser (on multiple devices). I prefer Firefox over Chrome. Any advice greatly appreciated.

Firefox is my default browser. I few days ago, it failed to open, and continues to do so. When I click on the icon, I get the blue spinning circle for a few seconds, then nothing. I have tried to refresh and reinstall, but nothing worked.

I had a whole bunch of open Firefox tabs and tab groups all carefully arranged just the way I wanted, then somehow a couple of tabs got moved to a new window (don't know how that happened, I didn't click the "Move Tab" and "Move To A New Window" menu options), and when I was trying to figure out how to move them back (not possible, apparently) the original window got accidentally closed -- and with it all my tabs and tab groups! When I reopened Firefox they just weren't there. Aagh! Clicking on History just shows the last tabs I accessed, not the full arrangement of groups and the many other tabs I haven't accessed in awhile but want to keep at the ready.

Can I get all that back? Or was relying on Firefox to organize my online work a bad idea?

On any video player that has a gradient, it breaks when I full-screen the video, showing as solid semi-opaque bars instead of the intended gradients.

This happens on any video player I've used that has a gradient, and is most noticeable on YouTube due to the double gradient.

It displays normally when I use snipping tool, so apologies for the bad quality on the second image.

I use Ublock Origin and Dark Reader, but this behaviour doesn't change when either is disabled.

There is a preference "media.gmp-widevinecdm.visible" When it is set to true we can see the Widevine addon in Add-ons and Themes. When Firefox is close the setting reverts to false and the addon is no longer visible.

Is this expected behaviour?

We cannot get Netflix to play DRM content. We are currently getting the UI3012 error. We updated the prefererence "media.gmp-widevinecdm.force-chromium-update".

I don't have a netflix account so I can't test on my PC, but setting the above preference on my PC and visiting netflix.com seems to be enough to trigger the installation of Widevine, as I have a folder called;

F:\Users\Tanya\Profiles\ownri05i.default\gmp-widevinecdm\4.10.2891.0

On my PC.

My brother, who is the one experiencing the issue, says he does not have the gmp-widevinecdm folder in his profile folder. However, before updating the force update preference he was getting the F7701-1003 error which changed to UI3012 after setting that preference.

The problem started when I updated his PC from a very old Windows 10 21H2 patch level (2486), to the current 21H2 patch level 5854 and updated Firefox 115.9.1 to Firefox 128.11.0

Will look into OS version upgrades later in the year, but for now I'd like to get Netflix working again.
