Hi, I've a problem with Firefox in Windows 10. I am used to open alot of tabs, like 40~80 websites in several windows. Never had an issue with this, nor crashes, unless there was a problem with 1 site. However, since yesterday in most windows my tabs are still open, but the websites are not there anymore. The screen/site is empty (see the attached screenshots for this). Yesterday when I was in such a tab and put my mouse-arrow where the web-address normally would be, I could see the address still, however, today after another re-start of my pc (hoping that would be solving the issue?) I notice now that also the website address has disappeared. I can of course try to re-install Firefox or do a repair, but I am afraid I'll lose all these sites, of which I was in the middle of reading them, saving/printing if required. And because there were so many, I am afraid I can't get them all back, since I've not made any notes of the sites I've opened. The plugins installed are: OpenH264 videocode and Widevine content decyrption module Extentions: Adblock and Adblockplus Adguard adblocker Awesome screenshot Download Youtube video Duplicate tabs closer Enchancer for Youtube Language Tool - Grammar and Style checker Privacy Badger uBlock origin Is there a fix for this, meaning that all sites will be restored, and not me searching again for these sites/information, and probably not finding/having them all back. Of course I won't mind to loose some, but I'd like to limit that as much as possible. I am attaching 2 screenshots: 1. with those blank new webpages, without reference to what site it was about, but some tabs still have the reference to the website, but no title/topic or website-address anymore; 2. with tabs where you still can see the site and it's address/topic. Thanks in advance for a sound, working solution.
