Until some days ago I could use the add on "Video Downloadhelper" without problems on my old Macbook Air (2017) with OS10.15.7 but suddenly the add on was not available anymore. I purchased a valid license for this add on. In the Firefox adjustments it was mentioned as deactivated. Could you please let me know, how I can activate the Video Downloadhelper again? Thanking you in advance for your kind support. Sincerely, Ulf Gaertner

With the "Drag & DropZones" mode of the "Selected Text Searchers" extension, one can highlight some text on the page and then "drag" it, whereupon a screen of defined search engines appear as an overlay on the page, allowing for "dropping" of the text on top of any of the search engines, initiating using that search engine to search for the highlighted text. This stops working after 148.0: the search engines overlay does not come up, replaced with only the non-working icon on the mouse cursor.

If I use extension 'Block Site' (shows up as a stop-sign shaped icon with a 'W' on it) to block a site, when I try to unblock it, it fails, with the below message:

"This operation cannot be performed in incognito mode. Please open the page in a regular browsing window and try again."

I am just clicking on the (whichever) site, from a search - not opening a private window... This extension used to work fine.

I did install DuckDuckGo browser, but removed it, as it was more trouble than it was worth. I would have to reboot my PC after each use before FireFox would connect.
