Diễn đàn hỗ trợ Firefox

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

After upgrading one machine from Fx 110.0.1 to Fx 112.0.1 (as per usual with "major" upgrades with the full install file) I noticed very high CPU usage when closing Fx, and it took quite some time to settle. I upgraded it to 112.0.2 via Help-About, but saw the same issue.

That is, starting Fx, opening a "private browsing window" and visit some site, say a search engine, then closing the private window and finally the first Fx window. (At the time I also see some spikes in CPU usage from the firewall software etc.)

Since I can’t have it like this, computer almost stalling for 30 sec, after closing Fx, and to see if there would be any update later to solve this issue, I uninstalled Fx 112.0.2 (I have complete backups of Fx profiles), and, just as a test, reinstalled Fx using the prior version of setup that I had, Fx 110.0.

Of course this meant a clean profile, not what any user wants to see (missing bookmarks is almost minor compared to all settings, incl. in add-ons, gathered over time. So I used the profile manager to change to my previously used default profile. After a restart I was greeted with a prompt that this couldn’t be done (since it may corrupt bookmarks(?) etc.) and I was left with the only options to abort (cancel) or create a new profile. Oh, great. I had not even used the newer ver. (Fx 112) to change or create anything, but I assume Mozilla could have something between the different versions.

So, I uninstalled Fx 110.0 (and of course in the process of creating a new profile/resetting settings it had reverted to "download updates in background", and I had to change that setting back, and stopped what was pending, during my tests trying to move it to my old profile). I installed Fx again, using the setup file for 112.0.1 and did a direct upgrade to 112.0.2, and pointed it to my old default profile, which had been used with 110.0.1 and during the first upgrade to 112.0.1.

Fx is working with my profile again, but it takes a very long time to close and (perhaps together with other software) consumes a lot of CPU, almost stalling the PC. During one such situation this morning I got two prompts for XULRunner "Could not determine any profile running in background task mode!" Never seen before. (I noticed that there now is a new folder in Roaming\Mozilla\Firefox\ called "Background Tasks Profiles".

Any help would be very much appreciated.

I know you cant help with part of it. When i launch a video i have bought on steam it now opens it on my default browser which is firefox, but it tells me its not up to date so i cant watch anything. at this point its forcing me to go back to chrome since it works.

Every Firefox update causes the need to confirm my identity thru an email or phone text to many of my bookmarked and frequently visited sites. Very annoying & time consuming.

Anything I can do or set to prevent this from happening?

Thanks,

After the latest update, trying to log into some sites, eg, https://web.emporiaenergy.com/#/login, the password field drops characters, takes 2 or 3 keystrokes to get a char to enter. Autofill fails miserably. What changed? This is unusable. BTW, tried with Chrome, no problem at all.

In the past week I have found that I am now unable to log into some websites, can no longer download pdfs from websites, or word docs from email. I have had issues trying to access chat functionality with my web hosting company. This has forced me to have to start using Chrome is many cases.

Firefox is my favorite browser and I want to continue using it, but if I am unable to access the websites I need to, when I need to then I will have to eventually jump ship.

Is this happening because of recent browser updates? From search from past issues people have had I've seen firewall settings a possibility, so could it be my firewall? Or are websites just not trying to support Firefox anymore?

Any information would be greatly appreciated.

Firefox used to open maximised but now opens in a half size window. I recently had an issue, following a Firefox update, of Google maps controls in the lower right corner missing. Also I could not toggle between map views. After advice from the forum I changed the "privacy.resistFingerprinting from 'false' to 'true'. This solved the Google maps problem but seems to have introduced the issue of Firefox opening in a 'half size' window. Any thoughts on what to do next, or do I live with it? Thanks - Chris

I am using Firefox version 112.02 with Windows 10 and am being told by some websites that my browser is out-of-date and that I cannot continue. Then today I was purchasing tickets for a show and the checkout was blocked by another message which said "Firefox Can’t Open This Page. To protect your security, **********.co.uk will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

Please advise how these measures can be removed or disabled as they are a perfect nuisance.

Hi there,

I'm trying to add multi-containers add on to a new Firefox install, it installs, but the icon doesnt show up. It's not hidden in the customise toolbar menu either. Have tried removing/re-adding, but it doesnt come up. It is possible to get to it by clicking the extensions icon, then clicking multi-container, but this isnt very user friendly. Is there a way to resolve this?

Thanks!

Twitter won't load in firefox latest version under windows 10. Connection problem, twitter running fine on android and windows chrome. So twitter is running fine just not on firefox windows 10.

Had to reinstall the Browser on my laptop after a harddrive replacement. I'm avoiding changing my password on my primary Firefox Account (Currently on a brand new FF Account using an email I typically don't use ) since that event will cause me to lose bookmarks etc on my primary FF account due to their encryption settings.

This is all because I can't remember my main password, for my primary FF Account email. And, I'm trying to not get locked out from login attempts.

At the moment my primary FF Account is logged in to my Desktop PC. Is there some way to view my password on my primary account that is currently logged in on my Desktop PC, without totally compromising my Account synced info?

I just want to resync everything to my laptop :/ That's the main problem I'm running in to, because there is no way to reset my password WITHOUT losing tons of my info. I'm pretty sure I don't have 2FA set up nor any alternative methods for password recovery. I wasn't prompted them.

My laptop crashed last night

I had to reboot windows. I had a lot of passwords saved on my firefox browser How can i recover these passwords? I need them to run software for college

No matter which option I select for opening a PDF (Open with Firefox, Open with Adobe Acrobat, or Save File) the PDF automatically saves itself to my Downloads folder. I do not want this. I don't want to constantly have to go in there and delete all these PDFs that I only needed to view once. Is this a feature or a bug? If it's a bug, please help me fix it guys. If it's a feature, that was a terrible decision from the Firefox dev team. I can't be the only one annoyed at this??

I want to block certain sites with the registry. But that method was too difficult for me. Can you elaborate on what to do? Please?

I'm at my wits' end. There are a few websites that just don't open for some reason. Either they don't load at all and I get a blank page or there's a problem with the way they load. I've done some troubleshooting. Figured it might be an add-on, safe mode didn't fix it. Tried a 'refresh'. Didn't fix it. Figured it might be corrupt cache after the first visit, but deleting cache didn't fix it.

Finally tried reinstalling Firefox and it did... but not for long. After the reinstall, the websites were accessible again no problem. But then the next time I closed Firefox and restarted it or shut down my computer, the problem was back. This is 100% consistent. No exceptions. Always reproduces the issue.

To give examples of websites that for some reason stop working: A couple of websites for a game I play (trackmania.exchange and trackmania.io) My work Outlook inbox and more generally the whole Office 365 suite online. The Twitter feed. For some reason the UI loads but the feed just says "Something went wrong. Try reloading". I'm sure there are others I haven't found yet, but for some reason I have no problem accessing YouTube, Google, Facebook, Instagram, etc.

I have no clue how to troubleshoot this any further. Something goes wrong after closing Firefox after reinstalling it. I can't keep reinstalling it every time I turn my computer on. I also don't want to have to use hibernate constantly to keep the first instance open.

Any ideas?

Thanks!

Several login pages don't load correctly, completely or at all since the last update. Binance homepage doesn't load the login menu (see attachment), direct url page just shows white screen. I also had some issues with logins on my health insurance site, downloading pdf's, everything just being incredibly slow, pages getting stuck, no loading icons. I cleared my cache and cookies, and it seems the problems got worse. I'm running a VPN, turning it off didn't fix these problems. Everything works fine in Brave. I tried troubleshooting mode, but once that was started up I didn't know what to do.
