My P/C started automatically in safe mode a few days ago. I took it to my repair guy & he fixed it. When he tried to open Firefox, error message as stated above was displayed. Since then, Browser does not seem to work as well as before. I believe all he did was to download a fresh copy. My question - should I try a Refresh of Firefox to remedy the problem or can you suggest anything else to try first?

Since the 44.0 update, Firefox takes at least 30 seconds and up to 2 minutes to start on my computer. Downgrading to 43.0.4 fixes this problem. I thought that 44.0.2 might work, since it reported a bug fix that sounded similar, so I upgraded to 44.0.2, but the problem came back and I am about to re-downgrade. I don't want to remain on the 43 version forever, so I am reporting my problem in hopes that other people may be having it as well and it may be something Mozilla can fix.

Details: I'm running a 64 bit version of Windows 10. I'm also using Avast anti-virsus, which may be a problem, but it works fine with Firefox 43.

I get a message: The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

With Firefox 45.0 just installed it did NOT appear. How do I know if it is truly eradicated from my home computers? RESET Firefox doesn't delete the old profile just replaces it. With Sync it use it didn't matter that one PC has a clean install of Windows 10, apparently. This annoying Firewall-lite to install appeared at EACH Firefox update on ALL my computers - (2) PC and (1) Mac. The Mac does not even have Sync enabled. I did have the PC's Synched including Add-Ons.

I first noticed this annoying possibly malicious promotion of its Firewall-lite addon when I was installing Flashblock. Somehow Firewall-lite was what was linked instead of Flashblock, in the top search result Install button. If open Flashblock page the Install button at the bottom is correct.

I used the Firefox RESET option on 3 computers, resetting all my passwords as the price to pay. NOW at each website first new login I have to right click for Fill Login (name/email) and right click - Fill Password. Thanks mybrowseraddon com

win 7 Pro. x64. FF up to date. have reviewed most of the pertinent tips and etc. There seems to be a key underlying question: should sync open using the accounts.firefox.com? There is one web address for support. A different one for accounts. Should I set up another for sync? The instructions do NOT make that clear. The error msg at sign-in using accounts. password is: 'unexpected error'. Well sure!!!! But quite useless info! Problems with sync are long standing and I quit from exhuastion and other surpassing demands. we try again. I strongly suspect that the problem is simply the correct password for the correct account---which would indicate: set up a new account: sync.firefox.com or such and with a new password. Is this correct? Once this is resolved, I can move on to other open tickets/questions of long standing!

Hello. I followed lots of forum posts with information on how to restore a .js session, and I've done this long ago. I must be doing something wrong but I renamed "upgrade.js-20160315153207" to sessionstore.js and moved it to my profile folder. Firefox won't load this .js file. I looked at the file and see all my url's in there so I know it's there. I tried following my threads including this one: https://support.mozilla.org/en-US/questions/1012716

I have firefox version 44.0.2. I appreciate any help. Thank you.

In help it says you can share a web page by clicking on the "share" icon. Which is on the far right of the bookmark, save, display, Mozilla Firefox start page, Start a conversation, share. However on my Firefox the "share" icon is not there. I'm trying to upload a screenshot, which I've done hundreds of times before on Safari, but it won't upload. How does one share??

Not impressed that all my extensions seems to have been removed together with all my adblocker settings.

It works fine for maybe 2 hours and then it stops loading any website. My other browsers still work. I have to force quit Firefox to get it to load pages again. It stops responding when I just quit the app so I have to force quit it. I've tried all the troubleshooting steps: Changing proxy, enabling/disabling firewall etc. but none of it seem to work. It's really annoying at this point! Any help?
