I use the default setting that all cookies be deleted when I shut down Firefox, and then hand-input dozens of exceptions. The Firefox update on November 11, 2025 -- and I didn't even click on install, I only downloaded it, then hesitated, being afraid that it costs me again hours to re-create what the update destroys, but Firefox went from download to automatic installation -- meant that Firefox wiped all cookie exceptions (list of cookies that are not deleted when I shut down Firefox). These exceptions are hours of work, and, additionally, every bank etc. now requires me to sign in and go through many-factor authentication anew. -- How do I restore the long list of cookie exceptions that the Firefox update just deleted?

+ The same update wiped all bookmark icons. My three dozen bookmarks in the bookmark toolbar now come with the 'globe' symbol rather than the bookmark-specific symbol, so I can't tell which bookmark is which. How do I restore the bookmark symbols that the Firefox update just destroyed?
