Firefox Community Forum

Hello, I originally installed Firefox in my work laptop and logged in to sync my stuff. Due to some company policies, I had to uninstall it. Eventually, I was able to overcome some oddities and finally could reinstall Firefox. But when I logged in, sync was neverending (matter of hours, if was just stuck); thus I refreshed it, but no luck whatsoever, still neverending sync. Tried a few refreshes and reinstalls until eventually everything was fine.

Unfortunately, during this process something must have been damaged as I lost most of my extensions and themes. So I decided to reinstall them one by one. For some of them everything went just OK, but some others (e.g. FoxyTabs) cannot be installed anymore, see screenshot. The path is:

1. Click add button
2. confirm I want to add the extension
3. that error is shown (translate from italian: An unexpected error occurred during the installation)

I really don't know what to do. Did my Firefox installation get corrupted or what?

Thanks a lot!

Hi, I have a problem with Youtube playback on my machine. Sometimes videos are playing and skipping few seconds, sometimes stopping/hanging and using a lot of CPU (I can hear CPU fan ramping up). It mostly happens when I play videos at 1080p and up. Sometimes video can start playing, then skip few seconds, play few more seconds and hang, sometimes after refresh it works fine, another time it works for like a minute and then again hangs/skips. I had this problem on FF 89, I've updated to 11x, still persisted, now I have FF 125.0.3 (64 bit). Things that i've tried: - enabling/disabling hardware acceleration in FF - enabling/disabling gpu hardware acceleration in Windows - changing some settings in about:config (fe. media.wmf.zero-copy-nv12-texture to false and gfx.direct3d11.reuse-decoder-device to false, and few more) - disabling and deleting addons

Hi I have lost all my bookmarks. I bought a new device. On downloading Firefox the the bookmarks toolbar was Google's. Now Firefox on my other devices has the the Google bookmarks toolbar. Help please.

Hey guys. Just bought a new pc with a RTX 4070 ti super GPU. FF is my browser, and when i google i see VSR is supported in FF. But watching videos in FF does not activate RTX VSR, it stays inactive in the Nvidea control panel.

When i use Chrome browser it works as it is supposed to, it says active and i can see the video quality is improved. Is the feature just broken in FF at the moment, or is there some settings i can change in FF to make it work today?

(i checked about:config and gfx.webrender.overlay-vp-super-resolution is set to true)

I have the same problem as described here [1]: when I open a markdown file in Firefox it uses itself as handler opening it in a new tab, which in turn opens it in a new tab, ... The solution suggested under [1] is how to make Firefox usable again, stopping it from open this particular markdown file. But it doesn't solve the actual problem: either Firefox is capable of rendering markdown in which case it should do it; or it's not in which case it shouldn't try. Does anyone have a thought on that?

It's a NIGHTMARE trying to read a web page! control C USED to work but they have messed with it and so it's really non functional as it only shows part of the page and HIDES a lot of it so that scrolling does not work! A real disaster now.

Google has it in for you and Duck Duck Go also, it's obvious a big war is going on and they do things to hinder. so wish you had not SOLD OUT THE MAIL. It is not better. I'd give a lot to go back to just how it used to be! No way am I doing any more updates! And I still get messages from others who say they agree with me.

They keep "updating" the internet but it is to take back the privacy we used to have. So many things don't work nice or right or even safe anymore!

I'm having a problem where certain websites does not show up as shortcuts on the startpage. Like for example reddit.com or twitter.com does not appear even though I visit those pages often and more than any other page. It doesn't make sense that a random website shows up immediately as I visit it once, but not the websites I visit often. So I have to type in manually in the search bar to get there instead of just clicking the shortcut on the startpage.

I COULD pin the websites on the startpage, but the pictures only show up as the automated pictures such as "R" or "T" for Reddit and Twitter respectively. I'm also having problems using my own pictures for the shortcuts and I'd rather fix the problem instead of having to pin websites as shortcuts. It also looks a bit ugly in my opinion.

This started happening after I switched Microsoft accounts on my PC and started using Firefox on another user account. By the time I switched, I was logged into the same account on two different users on my PC, and I synchronized several times. That other logged in user is now removed from my Firefox account and I also completely deleted the other user on my PC to free up space. I have completely uninstalled and reinstalled Firefox and deleted all the files on my PC, but it still doesn't work. I have checked in about:profiles and it says there is a "default-release" and "default" profile.

Verification of website says part of innovation project with Mozzilla A new A.I. site popped up called Solo which lists it as "a Mozilla Innovation Project" focused on developing an AI website builder for solopreneurs for free. The site is SOLO.ai and I need to know if this is affiliated with the "Mozilla Innovation Project" that the site says is part of mozilla? The person that corresponded with me is a Raj Singh
