I no longer see my LastPass password manager on FireFox. I'm using an IMAC Retina, 5K, 27", 2017, Ventura 13.7.8. It's always been at the top of the page. What can I do to bring it back?

Hi, I'd like to remove the rounded corners ( they are too big) everywhere in the Firefox browser. The suggestions I've found online aren't helping me. Do you have a solution for beginners?

Hello,

I have had an issue for a few months now where certain websites fail to load. This is most easily reproduced on https://addons.mozilla.org, where I am shown the error "An unexpected error occurred" on most pages, preventing me from installing addons.

This issue does not occur in a Private Window, in Troubleshooting mode or in Chrome or Brave, but persists in fresh installs of Firefox. In troubleshooting this issue, I have removed all program files, registry data, and app data pertaining to Mozilla / Firefox. In fresh installs, I can sometimes install an add-on or two before this error starts occuring. I have not imported any previous data.

I was previously installing from Chocolatey, but in my last clean install, I downloaded from the official website.

I am on Windows 10 and Firefox 157. I use Proton VPN (Paid) and have tried changing servers several times to no avail. Again, this only happens in Firefox in a standard window, Private Mode and Troubleshooting Mode are fine.

Screenshot 1 shows the issue from my most recent reinstall. I was able to install 1 add-on (SponsorBlock) before it started showing up. Removing the add-on doesn't fix the issue. Trying to access addons.mozilla.org via a search engine results in the tab icon loading for a second and no change happening on screen (Screenshot 2).

I experience similar issues on other websites, like trying to log into Bandcamp.com (logging in gives the error "There was a network error. Please try again."), but most sites work.

Loading https://addons.mozilla.org/en-US/firefox/ gives the following results in the Network Console:

Uncaught (in promise) TypeError: can't access property "pressed", target is null

I browse exclusively with Firefox on a Windows desktop. Edge is installed but unused. Even so, Firefox unpredictably starts as many as seven Edge Webview2 processes, which invariably bog the computer down. (Webview2 pops up only when I use Firefox and usually when nothing else of consequence is running; so Firefox seems the likeliest culprit.) Microsoft says that trying to uproot Webview2 will disable many apps and may end civilization. How can I prevent Firefox from invoking Webview2?

My Apple desktop crashes frequently in different applications (while in gmail, on Facebook, etc.) and it sends a report to Apple every time. It never does it if I use Safari. If I can reload Firefox to fix it please let me know how to do that. Thanks.

cant get rid of stupid thing that comes up saying i have a virus so i buy some stupid anti virus crap i dont buy things oclick here to remove it but it doesnt what kind of scam is this so i buy somethingn line says system alert

Yesterday (10/1/26) Firefox went through SEVERAL updates to v.157.0. Now, it behaves extremely buggy and locks up if I try to open more than one window. It was never this pathetic! I want to revert back to the previous version. Yes, I am running Win10.

Also, now it will not even close properly. I have to go into program manager to kill all of the subprocesses that have spawned. I DON'T LIKE THIS VERSION AT ALL!!!!!

I'd like to request a refund for the Mozilla VPN I paid for. My Last bill was on September 25, 2026 in the amount of $59.88 + $3.83 tax. I won't really be needing it and I am OK with the built-in VPN on Firefox. I am within the 30-day money-back guarantee. Thanks.

COPIED FIREFOX BOOKMARKS FROM MY HP COMPUTER TO MY DELL LAPTOP BY COPING THE HTML FILE OF BOOKMARKS TO MY DELL LAPTOP DESKTOP SCREEN AND IMPORTED THEM FROM THE DELL LAPTOP DESKTOP AS ADVISED. STILL DID NOT GET ANYTHING COPIED TO THE NEW FIREFOX INSTALLATION EVEN THOUGH IT STATED IT HAD COPIED 827 BOOKMARKS. NOTICED THAT THE FIREFOX SOFTWARE INSTALLED ON MY HP COMPUTER STATED THAT IT WAS WINDOWS 10 INSTALLATION. ORIGINALLY THE HP WAS WINDOWS 10 BUT UPGRADED IT WITH FREE MICROSOFT WINDOWS 11 BUT DID NOT UNINSTALL FIREFOX FROM IT AND REINSTALL FIREFOX AFTER THAT. THEREFORE THE FIREFOX BOOKMARKS ARE FOR A WINDOWS 10 INSTALL ON THE HP COMPUTER AND TECHNICALLY NOT A WINDOWS 11 EVEN THOUGH THE WINDOWS OS HAD BEEN UPGRADED TO WINDOWS 11. SO, I GUESS TO PERFORM THE ACTION I STATED ABOVE TO UNINSTALL FIREFOX ON THE HP COMPUTER AND REINSTALL IT ON THE HP COMPUTER IT IN ORDER TO GET IT TO WINDOWS 11 FOR BOOKMARKS? HOPEFULLY I WON'T LOSE THOSE FIREFOX BOOKMARKS?

i don't believe its memory issues because my PC has 61.6 GB of 474 GB free, and i never got these crashes before the update, with the same amount of data. dunno what else to add here, let me know if i need to provide something more

I have done thorough testing with other browsers, drivers for my headset, reinstallations and the common issue is the new firefox. when I change from my desktop speakers to my headset there has always been a slight delay in the crossover. however since the most recent update Firefox has made, Youtube shorts and videos dont load properly. this is only when using my headset. when you go to shorts, and scroll it will play them one after the next with no load time or at least very little. now however, it takes 10-15 seconds to load, but ONLY when i am using my wireless headset. Corsair Void Wireless Headset. I have done everything on my end, and after countless tests with other browsers it is only Firefox and has only starteed since the most recently update.
