Φόρουμ υποστήριξης - Firefox

Every time I open a new tab or go to a tab that I have open, when I come back after my computer has been asleep and try to search for something or refresh a tab, it will give me an error message. I have to close the tab and search again then it works, sometimes I have to do it 2 or 3 times to get it to work. This just started happening with MacOS Catalina 10.15.7 and FireFox 103.0.2 updates in the last few weeks. I tried restarting my computer and I deleted the Firefox app and reinstalled but nothing helps.

Audio file plays to end on Safari, but abruptly stops every time about 30% through on Firefox. MacBook Air OS 10.15.7 file URL https://podcasts.yarravalleyfm.org.au/ep/416 Grateful for advice.

I've installed lots of add-ons thru out the years and when I'm not using them, or just didn't like them, I just go to the "Add-ons" settings and press on "disable" thinking that's the end of the story. But I've become more privacy and security concerned as time passes and now I'm wondering if I should delete all the add-ons that I no longer have any use for, (and some useful ones but are very sketchy).

What I mean is that some add-ons "require" permission to everything you do in your web browser "to work properly" and well that's beyond sketchy. I recently used an old add-on and realized it worked perfectly even after over 2 years of it being disable, I mean even after multiple firefox updates. I realized that the add-on had "automatic updates" turned on so... even disabled it was updating in the background... therefore it was somewhat active.

Now I'm wondering if all of this sketchy add-ons that I've installed thru out the years that need all kinds of weird "permissions" like access to well... -everything- (passwords, history, credit cards, etc...) have been collecting all this data even after I disable them years ago?
