Hello guys! We are currently investigating this issue and hope a resolution soon. Can you recall which Firefox Version you were using prior to the update? We seem to have a hint that the issue may be linked to users updating from older versions than the immediate previous version. This information is certainly helpful! Hope to hear from you soon!
Thanks for letting us know you are having this issue. The developers at Mozilla are working on getting this sorted. In the meantime, some users have found success by creating a new Firefox Profile. Others resolved this by removing Adblock Plus using the the instructions in this link https://help.eyeo.com/en/adblockplus/un ... s?5de59f86, and reinstalling via https://adblockplus.org. Let us know if this helps!
I realize this is an old thread, but I've been having this issue & it's still ongoing (it's now Sept 14), others elsewhere have said ditching our FF profiles & starting over with a new one doesn't work, plus it seems odd to insist it's a corrupt FF user profile when people have the same ABP launch page problem with other browsers.
Thanks for reaching out to us! Have you already tried a new FF profile or a fresh reinstall? These steps tend to prove successful in more cases than not. We'd love to hear your feedback on this. Let us know if it works for you. In the meantime, The developers over at FF are still working on getting this resolved.
Some of the older issues were due to symptoms related to local storage, this issue is a different one with the same symptom if that makes sense. Users have resolved by creating a new Firefox profile.You can find instructions for doing so here. https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Multiple_profiles.
