something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

I recently got a new computer. Installed firefox onto it. Brought over my profile with all my data and bookmarks. But for the life of me, the page would just sporadically flicker. I tried messing with the settings; performance settings; hardware acceleration. I tried refreshing firefox. But nothing.

I know that it is possible, cause, in the past, I had extension doing exactly that. When I click on an active tab, Firefox just minimized it and went back to the last one I was looking at. But it was for the old version of Firefox. It wasn't compatibile with the new ver of the brawser. Can anyone can help me find some extension doing that please?

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

To upload/import bookmarks into Firefox, the file extension of JSON is required. However from old crashed computer, I exported bookmarks in Excel. Please help. Thanks

I'm using Firefox with Google as my default search engine. When ever I try to type in the Google search box, what I am typing appears in the address bar. I want to search in the Google search box as it is at eye level for what I am doing. I have tried all sorts of ideas from the web to fix this but no joy. Does anyone know how I disable this? Thank you

Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

Outlook is not working properly in Firefox. Works fine in other browsers but I prefer Firefox. It is only showing the first 20 or so e-mails, will not show e-mails in any other box, i.e sent etc.

So Mozilla supports privacy rights- and I've supported Mozilla for that reason- but they want Whatsapp to be censored for "misinformation" ? How does that go together? Whatsapp was supposed to be encrypted and not even Whatsapp was supposed to know the content of messages. How would they know about misinformation? And how do they get to decide what's misinformation now?

The comment windows are present but do not function. The youtube hosts are accepting comments from other folks. I wonder if some Firefox settings need adjustment so I can participate. If you reply I hope it goes straight to my email address as I nmay not find this site easily/again.

After updating to 125.0.1 (64 bit) all my existing tabs were wiped out. Restoring the tabs does not solve the problem. Every time I close Firefox the tabs disappear.

When I enter text in Firefox 125.0.1 for Netgear's firmware download page at https://www.netgear.com/support/download/ to search for "GS108Ev3" Ethernet Switch, I get no response. It works in Firefox Troubleshoot Mode and works with Chrome Browser.

After the last update my primary password prompt box is outlined in red. It was never outlined in red before the update. I cannot find any information for this issue. Anyone else experiencing this anomaly (at least it appears to be one since no one has reported it). Thanks

Whenever I go to youtube, it fails to work and leaves an error in the console similar to

Uncaught Error: Constructing ytd-app: [Exception... "File error: Corrupted" nsresult: "0x8052000b (NS_ERROR_FILE_CORRUPTED)" location: "JS frame :: https://www.youtube.com/s/desktop/050e6796/jsbin/desktop_polymer_enable_poly_si.vflset/desktop_polymer_enable_poly_si.js :: kCb :: line 9877" data: no]

I've determined that I can fix the problem by deleting my Firefox profile. I'd prefer to avoid this since there's a lot of useful history there. Is there a more targeted fix the problem I'm seeing?
