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.

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.?

Whenever I try to download a rar file, like a game from itch.io,0 it automatically fails and doesn't download even after retrying multiple times.

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

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.

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 wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

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

Hello,

I am wondering what if anything regarding settings, customization, data, etc is likely to break if I perform this update? THis has happened in the past and is why I turned auto update off. Should any intermediate updates be done to stepover/convert any of the data structures to a newer format?

Thanks, Steve

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 do not want the new update of firefox, and theres no way to shut off the updates. i can only switch to ask me when to install and manually install, not that i do NOT want to EVER install the latest firefox, because it truly SUCKS. it screwed up all the fonts everywhere on the web, somethings are huge and others are too small to read. i woke up a couple of days ago to an unreadable internet. i had to reinstall the last update before this one, start from scratch with all my passwords and a lot of hours of messing with my computer just to have it bearable and able to read my emails. now it keeps prompting me to install the latest. like every few hours i get an annoying pop up to install the latest. then to get it to go away i had to click on something, that downloaded it even though i dont want it. i seriously may have to switch browsers and abanadon you all completely because thats how bad your latest update is, and thats how much it sucks to not be able to stop it form harassing me every few hours to instal it....with no way to turn it off completely that i do not ever want the latest crap update.

I always was a fan of firefox 56.0. When ever the updates are available I decline. I got it before and had to redo some stuff the way I like it. I have heard others complain about these problems and now youtube is all messed up. Where I have my tabs there is some discoloration and the tabs are missing a lot of sites I had in them, I guess my computer did the latest update. How can I go back to FF 56.0?
