Firefox 52.9.0esr (32 bit) (WinXP SP-3) wants to disable my add-ons
All of a sudden, I get a message that one or more installed add-ons can't be verified & has been disabled. However, they seem to still work. But I get the message shown below every time I launch Firefox. This just started happening last week.
I've shown a picture of some of the "disabled" add-ons. However, I know for sure that Roboform is still working.
How can I get rid of these messages? Thank you in advance!

There has been an unfortunate issue with an intermediate certificate that had expired recently and this certificate was used to verify the signatures of extensions hosted on the Add-ons website. This expired certificate caused Firefox to distrust and disable all installed extensions. There have been Firefox updates released to address this issue (66.0.4 and 60.6.2 ESR),see:
- Help -> About Firefox
Users of older (unsupported) Firefox versions will have to install this new intermediate certificate manually via other ways for now.
