Firefox Support Forum

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

Since about two months ago, I haven't been able to update Firefox(or any other browser for that matter). I've tried the typical method of going to Preferences, checking for updates, but I can't get passed that point. I get this error message stating "Failed to check for updates."

Chrome was giving me much of the same issue, I've allowed GoogleUpdate on my firewall rules, restarted the PC and tried again. Still got the same error message. I have no other antivirus software installed on this device other than the Windows Defender default app. Firefox hasn't told what I should be allowing past my firewall so I haven't tried anything similar for Firefox.

I also tried uninstalling Firefox, but when I tried to reinstall, I couldn't finish that process because clicking on Download Now led me to this error message stating "Hmm. We’re having trouble finding that site.

We can’t connect to the server at download.mozilla.org."

I assumed this was maybe a DNS issue. I tried a DNS flush but that also was ineffective. I tried changing my DNS servers to 1.1.1.1 and 1.1.1.2, also tried other known DNS servers but that didn't work either.

In the meantime, I'd like to at least get an offline installer going because my current version is 110.0.1.

Thank you.

I have downloaded Firefox 113.0.1 for Windows x64 but the file seems to be corrupt. When I check the installation file with 7Zip Test Archive appeared a Warning Message due to a Checksum error. All others versions of Firefox downloaded can be checked correctly by 7Zip, but this installation file show an error message that I never have received. Is there a problem with the file? Thanks

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

It seems like no matter what I do, I can't get Firefox to download files from Google Drive. It loads for a moment, then it says "The page isn’t redirecting properly". I have confirmed that it's only Firefox because I can download files from Google Drive with Google Chrome. I have disabled Enhanced Tracking Protection, selecting the Standard Enhanced Tracking Protection Setting, and even refreshing Firefox. Though, I noticed that it only works on incognito mode for whatever reason.

About a week ago I started having trouble downloading large high resolution photo files. I have been downloading these files for work for over a year and they have always load very quick. I would click on the file and the entire photo file would be there instantly. However, for the past week these file do not download or download very slowly. I have checked internet speed, which is 310. I can also switch browsers and have no problem downloading the same files. So its not my computer and it not the internet, so something has changed with Firefox. Can you help?? I have used Firefox for over 20 years and don't want to change browsers, but I have to work and this downloading is a problem.

I was in italy when I first created my firefox account and by default it choose italian as language. All of my search results are in italian even though in browser settings I choose English as preffered language. Now I discovered that actually my firefox profile is in italian that's why I see results in italian. In the profile settings (https://accounts.firefox.com/settings), there is no option to change the language. Please help.

Earlier today (well, it's yesterday now) Firefox was updated to 116 and since then it won't download any images or other files from anywhere. I've set a default download directory and when I click "Save image as...", that image should appear in the preset directory but it doesn't. I have two extensions for downloading images and they work just fine, only the default function of firefox doesn't work. Here's a short video showing the problem:

I tried downgrading Firefox to 115.0.3 but that didn't fix the problem and I'm out of ideas how to fix it. I'm 100% sure it's a firefox problem bc I tried saving images with Opera and Chromium and there was not a single problem with that task in either of these browsers.

I am trying to install 32 version of Firefox on a VM running RHEL8.6.

I sourced the installer from https://download-installer.cdn.mozilla.net/pub/firefox/releases/115.1.0esr/linux-i686/en-US/firefox-115.1.0esr.tar.bz2 here and i followed the installation instructions mentioned here .

After the installation is done, whenever I try to run Firefox, I get the following error

-bash: /usr/local/bin/firefox: No such file or directory

I checked the environment variable and it was et correctly.

Please let me know where I am going wrong.

Thank you.

I want the version (which i assume is the ESR one) OFF my computer. I have downloaded a "regular version" (116.0.3) and have followed all instructions I have found on this site. It gets to a point and says it can't find the file. There is no README or Install file in the download so I am stuck. Please help me because I want the ESR version GONE!!! Thanks for any help! R

I will be moving all of my data to a new laptop and want to know if I need to have both my personal Firefox profile and the "default-release" profile backed up. The "default" one is over 3GB and has over 20k files in it, and my personal one is only 113 MB with 1300 files — and my thumb drive needs all the extra space it can get. (Why would the "default-release" profile be so much larger than my personal one?)

The old laptop runs on Windows and the new one will have the Linux OS. Will that make a difference in using a backed up Firefox profile? I mean, will the data still work in the new OS?

HI, I had a PC crash and I am now unable to use my old Installation, so I reinstalled Windows anew. Before that I could save some stuff.

I have saved the whole Firefox Profile Folder and the Installation.

Now I just copied the Key3 and Key4 + logins.json Files to my new Profile Folder (places, booksmarks, etc too) but nothing will be applied.

What do I have to do to get my old stuff back? Especially my Login Data and Bookmarks? Why does this not work anymore? Is it due to different Versions? Although I am pretty sure that my old FF was up to date. Is there a Log File?

Also I have an old logins.csv, but it has corrupt/incorrect symbols in it.

Every few days, Firefox makes me log back in again to my account and "create" a new profile version - the message I get is that I have launched an older version, and can only EXIT or CREATE NEW PROFILE. The problem is when I have to do this, I lose all the pinned tabs I had open, also I have to log into Gmail each time and generally set the profile up again. I can then access my bookmarks and containers but not the tabs I had open.

Is there a way to stop Firefox from forcing me to relaunch my profile each time? Its frustrating to lose the pinned data and have to log back into my Firefox profile, then Gmail, then try to figure out where I was at last. Note, the pinned tabs are not things I need to bookmark but rather a running list of tasks/things I need to complete - and unfortunately I don't know when I will be forced to launch a new profile but don't want to create a bookmark each time for temporary tabs... for example, last night I was just in the middle of planning a trip so had a few tabs open to come back to, but when I logged into my laptop this morning, I was forced to create a new profile and have lost these tabs I had pinned.

Firefox cannot access my bank account. Bank says hello to my name when I log in, but then keeps saying "loading" and can never show me what is in my bank accounts. Why?

How do I download 68.10 ESR? Later versions break my files. Don't know why and can not get newer files. All I get is newest version, not the one I need. I can get to the older version directory. But which file do I get?????????

I currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.
