Hi, your browser has a new name. What I mean is, every browser sends a "user agent string" with requests and some sites use that to check for compatibility. Your Firefox told this forum Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0'''/QB3LsTFr-56''' That last bit is not supposed to be there. Recently, '''Avast AntiTrack''' has been identified as doing that sort of thing. If you have that add-on/program/feature, you could look into turning off whatever that behavior is called. ''To check for a browser extension and potentially find its Options panel, either:'' * Ctrl+Shift+a (Mac: Command+Shift+a) * "3-bar" menu button (or Tools menu) > Add-ons * type or paste '''about:addons''' in the address bar and press Enter/Return In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading. Do you have Avast AntiTrack? If so, click its name to show the Details panel. Here you may also see a link to Options (depending on the design of the extension) or you can click the slider switch to disable it temporarily.
