Hi there,
Have just created an Acc here as think I've been suffering the same or similar problems with Firefox 129.0.1 64bit whilst I'm using the latest
version of Avast on a Win10 laptop.
My problem was very intermittent, would be browsing just fine and then suddenly evertime I entered a search term in Google, my regular search
engine, nothing would come back and the search field I'd filled in would become blank. Was convinced it was an issue with Firefox and have been
trying to resolve it with help from some of the Mozilla forum members.
Had found a work around by going to a Private Window which always worked on any search. Strange though that on returning to a normal browser
window I able to enter search terms again and get responses as expected.
Another issue I was experiencing was with having my Gmial email account open I would often see a yellow notification banner at the top saying something along the lines "There was a system problem error No #001". I think both issues started at the same time but can't be 100% certain.
Have been jumping through various hoops with help from the Mozilla Firefox forum all of which failed to resolve the issue, was starting to consider ditching
Firefox and someone suggested disabling Avast as they saw something in the screenshots I posted of the troubleshooting tool within Firefox. It was the last thing I tried, currently have Avast disabled and everything works as it should with no problems searching and no issues with Gmail either. From what I've read here it seems that the Webshield is the culprit so will re-enable the other shields and see how that goes sort term.
Haven't read through all of this thread but has anybody tried uninstalling Avast and doing a fresh install? Have been using Firefox and Avast Free for many years now and never had issues like this previously and would like to keep both.
Only ever had one major issue and that was with Comodo Free Firewall which broke the wifi network adaptor on my sons PC. Days spent sorting that out and have steered clear of Comodo since, their support was none existent, luckily someone on their forum had created their own tool to clear the problem.
