Browser Tab Crashing

Hi,

Corrupted browser cache and extensions are some of the things that can cause your browser to crash. To isolate your concern, we'd like to ask the following:

• Have you made any recent changes on your device prior to your concern?
• Have you tried using a different browser other than the ones mentioned above? If yes, did you encounter the same error?
• What are the troubleshooting steps that you've performed to resolve your concern?

To rule out any performance issues, we suggest that you replicate your concern while you're in the clean boot environment and check if the issue persists. To do this, follow the steps provided on this

link.

We'll appreciate if you can send us an update.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Add-Ons for Firefox crash since update to 80

I left Firefox open over night and attempted to login to LastPass this morning - all the addons crashed. I had Firefox Task Manager open at the time and before attempting the login all addons were in the list and not using very much resources. After attempting login, all of the addons disappeared from the Firefox Task Manager list.

I will try the additional suggestions.

If I want to try a new profile without losing my saved/sync profile (and hopefully with the option of syncing my data back into the new profile) what steps should I take? Or is it just a given that if it is profile corruption, the sync profile is junk...?

Thanks!
