I have a home website that was written using php well over 10 years ago. Except for family updates, it has changed little and displayed correctly using firefox and other browsers. Firefox is my preferred browser. A couple of months ago, it stopped displaying correctly in firefox but continues to display correctly w/o issues in Edge, and other browsers.

I note it displays in a basic form in firefox, links to other pages and content are shown and operable, but not displayed (correctly) as it does in Edge and others. I am on the latest version of Win Pro 10.

I posted the problem the end of August and received a number of suggestions. I went through the steps suggested (using troubleshoot amongst other suggestions) and none of the suggestions resolved the issue. My suspicion is that something in a relatively recent update of firefox has issues with my php based code. I do not use a "web tool" but write the source myself. I started writing websites with html decades ago and got the bug to use php years back.

If anyone has the interest (or curiosity) to look at the website in firefox and edge and my source code and see if they see the issue I would be glad provide the link to my website.

I was using Firefox, had one window open...browser was moving slowly so closed it. When I went to reopen-even in safe mode-it loads windows I had open and then suddenly crashes...I cannot refresh it as I have a lot of custom settings and bookmarks...this is the crash report I keep getting, can anyone help me please?

Hello,

I have a PC with Windows Seven, and a local network 1Gb/s (wired, no Wifi) with a NAS. When Firefox is open, the speed of my local network slow down. It takes about 30 seconds to open a big picture on the NAS when Firefox is open, and 0.5 s when Firefox is closed. Same thing for video. I can't read a video when Firefox is open. With Chrome or other browser all is ok... Firefox version is 91.0.2 64 bits, but same issue with previous version.

I have made a new profile, a new install of Firefox, shut down my firewall and Antivirus, Opening Firefox in safe mode, repair Firefox, but no effect...

Any help will be extremely appreciated!

Thanks!

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

When I go to google.com and do a search the results page has the "tools" button but it does not work. The "people also ask" categories are also broken (they will not expand), and, if I click the "images" filter button to view images associated with my search it either shows no images (or only a few images) and a bunch of blank boxes. I have found that if I hold the shift key and click the reload button everything is back and working properly until the next time I do a google.com search, then it is back to the same odd behavior. So, my assumption here is that either a cookie or some site data is corrupting the results page for my search. Running Firefox 92.0 (64-bit) on a Windows 7 Dell machine and everything was working fine until about two months ago. Also, Chrome does not show the same behavior. BTW. I have also done everything I have found that was recommended to fix Firefox issues with Google search. Run Firefox in private mode, run without plugins, changed themes, created new profile, I even completely uninstalled Firefox and did a clean install all with the same results. Any help is appreciated. It is almost got me ready to move back to Chrome.

Hi, The program SEEMS to start but Firefox does not load one singel page. I get no errormessage but firefox does not even try to open pages.

Also, if I try to go into "settings" nothing happens (no errormessage, but settings does not open).

I have tried to uninstall and reinstall Firefox. Does not help.

If I try some other bowser everything works fine. The problem started after I did a total uninstallation of Office365 (does not need to be depending on it but it could be a connection).

Have searched the web without finding a solution and now I ask for help here, I really do want to keep using Firefox but currently it is impossible.

I am using Linux Mint 6.0.3.1 , and my Mozilla Firefox version is 77.0.1 . My Firefox will not update, neither automatically nor when prompted. When I go to all the pages for downloading and installing the newest Firefox, I am always able to download a package, which appears as a folder labeled " firefox-89.0.2.tar.bz2 " but then I cannot install it, it just appears as a folder full of files that will not run. I have tried following the command lines in the terminal that these pages claim will make the new version run, but I always just get a response like "no such command" or "no file exists." Shouldn't there be some relatively simple and reliable path to just get firefox 89 onto my computer?

I store passwords on firefox account and use sync to share passwords across devices. I did not delete any passwords on any device. recently, I saw that only google account passwords are missing and rest passwords are intact in saved passwords. my google passwords have been stored since a long time. all my old and recent stored passwords are shown in firefox but only my google account passwords are gone on all the devices. I tried login-backup.json but there is no change in passwords shown. need help.

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

Upon the subject action, Windows 10 takes a system/memory dump, sends it to Microsoft, and automatically restarts. Firefox appears to be initializing for about 3 seconds (after clicking its shortcut) and then the crash occurs. The display of the initial Firefox landing page is not obtained.

The blue screen of death (BSOD) has this message: KMODE EXCEPTION NOT HANDLED

Also, the networking software (NETGEAR) is rendered inoperable and must be re-installed upon Windows restart. Otherwise, my system is stable. Maintenance is regularly applied as it becomes available.

Firefox was a delight to use. But now not so much, as it's unavailable as described above.

If anyone has a fix, or a suggestion for obtaining one, it would be gratefully appreciated. Thanks!

I have download set to always ask and consequently always get the, "What should Firefox do with this file?" dialogue box. 9 times out of 10 I choose, "Open with ... ". 10 times out of 10 Firefox also downloads the file. How can I stop FireFox downloading files I don't want ?

I have an older PC but it was working fine with Netflix and Prime Video until this latest update (v89.0). It seems that when I try to go to Netflix or Amazon Prime Video the browser crashes almost instantly, and usually shuts my whole computer off. It doesn't go to a blue screen, the computer just decides it's time to reboot. Now again, I'm using an older machine (and I can't afford a new one), but this was never a problem until this latest version of Firefox.

I am also not a fan of the aesthetics in this version and I'm wondering if I can revert back to an older version where the crashing was less frequent. Any help would be appreciated.

System is linux fedora up to date

Suggestions and help are welcome to solve the problem...

Firefox was one of the system updates I installed today on my Linux Mint 19.3. I updated it and discovered all history and bookmarks are gone. I have no Old Firefox Data folder. I tried about:profiles but the only other profile is the default Linux one. I tried to Restore from Import and Backup in Manage Bookmarks for several different dates, but only get "Unable to process the backup file" error. I also tried to choose several .json files from the STG-backups-FF-8x folders in Linux Downloads directory, but it doesn't seem to do anything. I've tried using Timeshift to restore from previous system dates, but it would only create Firefox folders with the same outcomes as above. I don't really care about history, but I have a lot of bookmarks that would be very difficult to recreate.

Thanks, in advance, for any help getting my bookmarks back!

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

Hi there, I'm having trouble opening firefox that suddenly didn't open after I've used it as usual. When I've closed it, I've put the macbook on sleep mode and then reopen it after 10 minutes and tried to open firefox as always. It didn't. I'm trying to figure it out and I've followed all the possible paths on Mozzilla's support and others blogs, but none of them worked out. I've tried also to uninstall and re install firefox from scratch, but nothing happens: I still get the message. At this point I don't care if I need a fresh start, I have a bookmark's backups so, how can I really uninstall Firefox and install it from the beginning? Is there a hidden folder I'm missing? Thank you in advance

I really try to find an answer online but looks like nobody find this to be an issue. Of course i have my password vault locked with a master password. But remembered logins on websites like Google and Facebook are secured by cookie login. Which not require my master password. So when someone use my computer unsolicited, this person gets instant access to my GMail/Facebook.

So how to protect per-logged in pages without resetting cookie data? Because i liked to benefit from instant access to al those website so i don't have to login everywhere any moment i start Firefox.
