Hi, my firefox started to crash regularly for a few months. I have seen it crash while on idle, while changing tabs, while opening ne tabs... i.e. no repetable pattern. Morever, I couldn't figure out the reason since all the crash reports turned different reasons for each crush. It has now become hourly crashes which really started to affect my workflow. Could you please help?

Can you run a memory test on your system?

Hi, I have just ran the macos diagnostic program and it didn't return anything as faulty/wrong.

What were you doing at the time? surfing, watching a clip, reading something . . . .

Is this with all websites/pages, some, a few?


Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi, I was reading something and while switching to a new tab it occurred.

Unfortunately, this has been happening regardless of the websites I have open or regardless of the activities I am doing and since it may happen 4-5 times in an hour or not for 3-4 hours at all I can't pinpoint it and if I didn't encounter it in the safe mode, it won't show that it didn't happen unless I use safe mode for 1 or 2 days. But I have some extensions that I cannot forgo for 2 days (password manager, vpn for work) I can't realise this test case.

Do you have any other suggestions?

Btw, thank you for your taking time to help me with this.

I understand about not giving up your add-ons. I am still using v54 because the add-ons I have won't work with the current Quantum browsers. However, if an ad-on is causing issues, the first thing to do is find out which one.

It could be the work of one of your add-ons, or it could be Hardware Acceleration.
How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager.
Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again.

Let us know who the suspect is, detective.

Hi, thank you for your understanding. I'll follow your advice and report back here as soon as I find the culprit.

Hi, I have tested with disabling all of my addons in batches and didn't encounter any issues. Howevery, I tested with different number of tabs and observed crashes when I have 3 or more windows open and have more than 20 tabs open in total. But task manager didn't report any troubled tabs. So the problem could be with too many tabs, hence memory?

Hi,

Do you have any updates?

more options

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.


Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.
