Description

I have a similar issue to #41: Video title and description get replaced with the ones from a different video.
The issue happens on every page (home, playlist, watch) and is persistent across:

signed in or out of youtube
different firefox tab container
rebooting

It seems the wrong title/desc somehow got into the cache and gets reused every time. I think I had those two videos next to each other in my "watch later" playlist. The cache pollution might be becaue I removed the other video (where the title got taken from) from the list and this one moved up one spot, but that's just speculation.
I think a simple "delete from cache" option would fix this, at least most of the time. It does revert if I uncheck the title/description replacement option and reload the page.

Environment

Yep, this is really embarassing... I'll see what a can do to release a quickfix, and also add a cache cleaner button in the popup / settings page.

Does it happens for a lot of videos or just a few? Have you watched thoses videos or not? (to know if the cache get "corrupt" when the video is watched or when browsing)

I've only noticed it on this one, so very rarely. I did watch part of the linked video, but not all of it and I think I never watched the other one, not really sure though. I have a strong suspicion it happened when modifying the playlist, possibly while watching the video.

Just released v2.12.0
Improved cache management & Added a btn for cache clearing in the popup.

Now that the add-on is popular on Mozilla, it need manual approval so the release won't be available before a few days unfortunately. You can still get it from the release and install it manually if you want to try.

I could'nt reproduce your issue, so I can't tell if it is fixed or not so let me know if you encounter it again, especially if notice a specific pattern. I will have a deeper look at this issue next week.

Sorry for the late reply! I had to wait until Firefox pushes the update since I sadly couldn't get it installed manually.

It updated now to 2.12.3 and the wrong title/desc fixed itself even without me needing to use the "clear cache" function.
Thank you so much for the quick fix!
