NOTE: I have made a video to show the problem, so if my explanation isn't clear, please watch this.

The problem arises only when I try to access the options tab. As soon as I have the options tab open, my PC's memory use skyrockets and doesn't come down, Firefox stalls completely and I have to close FF through the task manager.

This problem has never occured in the past, this has only been happening since a day or 2 ago.

I tried to disable all the add-ons, plug-ins, have the standard light theme. Nothing changed.

I don't really enjoy having to use safemode everytime I want to access the options tab.

Thanks for reading

Does that mean there is no problem using Safe Mode?

https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

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.

Yes, when running FF in safe mode, the problem doesn't arise. I disabled all the add-ons, plug-ins, disabled hardware acceleration in safe mode, tried to open the options tab with safe mode off, and the problem persisted.

That's why I'm so puzzled!

I even force updated Windows, got rid of Avira and got Panda instead...
