Firefox Community Forum

My mail checker extension isn't working right in Firefox. Extension Link I was able to find an error using Developer Options but I don't know if the error is even related to the extension or if it is even useful. If anyone would help me, I would be very grateful.

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

Sir/ Madam,

    It is delight to use and experience with Firefox Mozilla browser. I request to  make Firefox Mozilla as main.

After updating Firefox yesterday, when I use the search bar, switching between my custom search engines can only be done via clicking on a drop down menu at the left end of the search bar and selecting one with the mouse cursor. Previously, I could select my preferred search engine by using the up or down keys to cycle through them while typing a search, then hitting enter when the one I wanted was highlighted. Having to switch from keyboard to mousepad while typing a search is really annoying, I found the old way much more convenient. Is there a way to revert this, and put the search engines back at the bottom of the search suggestions, where I can access them with arrow keys?

Also, when I search now, the search stays in the search bar instead of changing to a URL, and I have to click a little internet globe icon at the right end of the bar for it to show the URL. This is also kind of annoying. Is there a way to turn this off, and just set it to show the URL every time?

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

I own a website that has chat rooms for each of my advisors. As of 2 days ago they are all having issues. I have them login with Firefox but now asking them to use Google Chrome...............low and behold it works

Whats the issue as i believe it started with the latest Firefox update

Thanks so much

When I download Firefox initially I am able to set the home page the way I want with the shortcuts I use. After a few weeks the shortcuts disappear and the only way to get them back is to delete Firefox and reinstall. I am also not able to save bookmarks anymore. This has the same resolution methods.

This has happened 3 times already.

Hi Fresh reinstall WIn10Pro home office pc -- want to ensure OS (WIn10pro x64) doesn't alter behind the scenes.

Want to prevent MScopilot or other rogue AI is not hiding changes unclear/unknown to user. Pc Admins and also PC std users

Have FF v140 syncing to a Msoutlook userid and have donated under that id. The donwloaded install was done via a private window as Edge had to be used.

New installs of everything. Full virus scans etc. latest updates. But still seems like MS trying to prevent using FF unaltered.

Is it best to set up a profile and then disconnect sync; then reset FF periodically and turn sync back on? Some IT people said they've done that for a while.

Are local windows users not supposed to be able to save FF settings?

Are we inviting in MS by syncing and/or donating to Mozilla / Firefox with outlook.com addresses?

Thanks.

Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

HI I cannot add an additional tab on top to open. I usually had no problem I need to open 6 to 8 tabs a day for work. Did firefox add a new version? every time I open an additional tab it closes the one I have open.

I don't know what happened is this a new version opened in fire fox.

Thank Linda

Hi community,

Since the last Firefox update, I’ve noticed that many websites load as a blank white page on the first attempt. The only way to get the content to appear is by refreshing the page manually (Ctrl+R).

This happens randomly on both static and dynamic websites — sometimes even on Firefox’s own support pages. I’ve already tried:

Clearing cache and cookies

Disabling all extensions

Running Firefox in Troubleshoot Mode

But the issue still occurs. No errors in the console either.

Is this a known issue with a recent update? Or could it be related to hardware acceleration, DNS, or caching settings?

Would appreciate any advice or similar experiences!

Bonjour, Je veux modifier ces sites webs recommandés. Des "top sites" ça s'appelle je crois. J'ai regardé sur le net mais j'ai pas vu comment les modifier. J'ai par exemple, pas besoin de Le Monde ou de Reddit. Cordialement, Un utilisateur
