I mistakenly deleted my firefox browser, I am running Mac OS 10.7.5 with a SSD on a Mac Pro desktop. I have been unable to download a new firefox browser because of the OS and hardware limitations. I sorely miss firefox. Is there any way to get an older version of firefox which will run on my computer? adnicastri@aol.com

Firefox 78.0.1 hangs trying to access websites but other browsers can

I have been using firefox for years and am very happy with it. I have a Dell optiplex 7010 desktop. I am running Ubuntu 18.04.4 LTS. I do not have a firewall turned on. Apparently, my desktop browser was updated to Firefox 78.0.1 (64-bit) on 7-1-2020. Since that time, I have been unable to access any websites from Firefox including mozilla.org. I am connected through WiFi. After downloading the Opera browser I have been able to access any website with no problems. I read community troubleshooting on this issue and tried various fixes including turning off IPv6. I read the community article about turning off my personal firewall. I was unaware of using any firewall so I installed Gufw Firewall 18.04.0. Running this program shows my firewall status is "OFF". I checked my AT&T modem and could not find any firewall settings that specifically mentioned Firefox. I would like to continue using Firefox since I use it on my phone and laptop also use it.

My laptop is a Dell Vostro 1520 running Ubuntu 18.04.2 LTS 64 bit. It also accesses the internet through the same WiFi. It currently has no problems loading web sites with Firefox version 78.0.1

Please help.

Hello,

My Firefox routinely shuts down while I'm using my 2018 Macbook Pro, and the problem began when I updated my IOS to Big Sur This is a systemic problem with non-native apps ever since installing Big Sur. Apple won't address the problem unless I confirm that my non-native apps are compatible with Big Sur. Can you please confirm the most updated version of the Firefox Browser is compatible with Apple's Big Sur IOS? Can you also let me know if other users have experienced problems and if there is any fix?

I just used pacman to update to the latest Firefox, but the tab crashed each time I open a new web page ( I can open settings, about:xxx and etc... ). I tried Troubleshoot Firefox crashes and it did not crash in troubleshoot mode. Then I tried extensions, themes and hardware acceleration issues to solve common Firefox problems https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems but non of these options solved the problem. I disabled all extensions, themes and hardware acceleration, and it reported the same error.

incorrect checksums of downloaded Firefox

Every time I download a new release of Firefox (win64 german), I check the downloaded file at virustotal and check the hashes published under http://releases.mozilla.org/pub/firefox/releases/<Version>, e.g. http://releases.mozilla.org/pub/firefox/releases/78.0.1/SHA256SUMS Up until release 77.0 the hashes matched but for 77.0.1 and also the current release 78.0.1 the hashes do not match, neither SHA256 nor SHA512. For "win64/de/Firefox Setup 78.0.1.exe" the SHA256 hash should be 56cff68e3f0cb76a6404d675f7e1bacc40ebaba7bbb5cadcb4950378656ab0a6 but the calculated hash is 8e69755f257aba44b6bbe5079e17f3bff8b62ddc27de9e1c479686e9ad871dfb When checking at virustotal, the file is recognized as scanned before and the displayed hash is the one I calculated, so at least my downloaded file is equal to the file other persons downloaded. Could it be that since v77.0.1 the published hashes are incorrect?

First, I just had a major system crash, had to re-install Linux Mint and through my own stupidity, relied on the wrong backups for my firefox configuration. So I lost my Firefox 52 install with all of my extensions (that still worked). Now, I'm running v. 57 Quantum, and a few things aren't working correctly.

First, the MAJOR problem: when I open a link from a bookmark, it's clobbering an existing tab that I was using (that's why it was open, obviously). That is completely unsat and can not be allowed to continue. How do I correct this? I can't find the option under settings-->tabs to fix this problem.

Second issue (major annoyance): I can no longer create a bookmark directly in a bookmark folder on the bookmark toolbar. I used to be able to open that bookmark folder, and the first option was to bookmark the currently open tab. That option has vanished, and i use that all the time. How do I restore that?

Actually, one more issue: I have two tabs that are pinned and are supposed to be protected (i.e., nothing can clobber them, and I can't close them without deliberately turning the protection off (context menu right-clicking on tab). I need that back, because for some reason, firefox thinks it's ok to open a bookmark in those tabs, too, when it most definitely is NOT ok.

Thanks, Jim Graham

The installation progress bar stops at about 75% and then a message appears saying, ‘Hmm. For some reason, we could not install Firefox. Choose OK to start again’. BUT it won’t start again and if I try to download from your website, the whole process happens again. This is very frustrating as many of the websites I use, are linked to Firefox. Please advise.

I am using Firefox-ESR on my Kali linux distro. I am unable to load any webpages on Firefox but other browsers can load. I tried all the steps like clearing every history, cache, etc. I have even reinstalled several times but it is only loads for 2-3 seconds and shows a white blank page and nothing else. I have gone through your tutorial of "Firefox can't load but other browsers can" but it is not helping. There is no problem of proxy either.

Edit Update : I need the Firefox-ESR installed as default. I downloaded new version Firefox-ESR=78.11.0esr from Firefox download page and it loads webpages. But the latest Firefox downloaded from apt is Firefox-ESR=78.10.0esr. I cannot update Firefox as new downloaded version has executable file name as 'firefox' but default has executable file as 'firefox-esr' in '/usr/lib'. I have two different versions of Firefox-ESR installed now because of the installation procedure given in Firefox install tutorial page. I am also not able to find the new version browser in 'x-www-browser' in 'update-alternatives' to set it as default. I want the Firefox installed with all features as default one. I think I have not installed new version of Firefox-ESR correctly. I just want to update Firefox but not to install another version of it. Thank you.

MacOS Catalina 10.15.7 Firefox 88.0.1 (64-bit)

All recent Firefox versions have killer bugs.

A new one was actually trying to login here. The error message said 'Cookies must be enabled' and I couldn't get further. Cookies *were* enabled! I shut down Firefox, and re-opened, and all was then OK.

. Web pages with scripts are often completely blank. . Pop-ups are often blank. If not they often don't work, like (critically) Ebay login. . View source (CMD U) works for new pages. However doesn't update if the source page changes.

 I do use <CMD U> from the changed front page.

A silly one is that the keypress to 'Copy Link' was deviously 'A', but not shown. It has now changed to 'L' and still not shown. Why? I very much prefer Firefox, and all the many shortcuts are memorised (well bar 'L' (8-)# )

However I so often now have to use Safari or Chrome to get around the bugs. This is a pain as the interfaces are different, and specifically 'View Source' never has a shortcut key. They also have their own bugs!

Sir/Ma'am,

My system is a standard install, and when I open Firefox, click Help, About Firefox, and then click the linked word (Mozilla) "Firefox is designed by Mozilla" it takes me to "www firefox com cn" ?

Is the version of Firefox in the Linux repositories the China version with an American facelift?

I know you all do not have command and control of this, but I thought someone should be aware that the default Firefox browser for Linux installs seems to be the CCP Firefox and not American version. With all the CISA activity, it might be something to look into.

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?

Firefox slow to load, 20-30 seconds. Appears is opening more than one instance with a single click. When it does load it sometimes comes up with the last page I had open even tough I closed it out properly. Sometimes get error msg that must close out 2nd Firefox before can start Firefox but saying yes results in the current open window closing. This started yesterday and the latest version of Firefox was automatically installed yesterday? Window 7. Cleared cash. Disabled all add on's etc. No help. Close out Firefox and Task Mngr show no Firefox running. Start Firefox and Task mngr shows four/five Firefox running. This started yesterday and the latest version of Firefox was automatically updated yesterday. Any ideas.

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

As the question says. I updated my Mac (2018 MacBook Pro) to the most recent OS (Catalina), I've uninstalled and reinstalled Firefox like 6 times, cleared my trash and any and all Firefox files, and deleted all profiles, made a new default one, and then deleted that one when it still wouldn't start, and restarted my laptop more than once. I cannot seem to get it to start no matter what I do! I've tried every fix I can find online. Every time I try to launch Firefox, it appears in the dash for a second and immediately shuts down. Trying to start in Safe Mode doesn't work either. Firefox used to work, but then I force quit it *once* because I was quitting all applications I wasn't using. Now it won't work at all no matter what I do. How do I fix this?
