was looking for something like that in extensions, user scripts were not working properly for me but this works just fine.

ekah·16 Aug 2026

It worked well for a little while but has become a veritable resource hog on my system. I work with a big amount of tabs and workspace. I take advantage of Firefox sleeping tabs to organize everything with a minimum impact on my system. The problem is every single time I try to activate this add-on, I've notice a huge spike of ram usage for no reason at all. I'm talking about my ram consumption going from 4GB (due to the amount of tabs I work with) up to a total of more than 16GB the moment this add-on goes on. Making the browser totally unusable. This not normal. After trouble shooting all add-ons I've been using until now, the culprit was PhotoShow. The moment I disabled PhotoShow, everything went back to normal. While this add-on has really useful features, at it's current state, I cannot recommend it at all until this problem is looked into. --- Ver. 4.89.2 seems not cause any issue. I will continue to monitor it on my end to see how it goes while keeping an eye on the future patchnote. Hopefully a futur fix will solve my issue. I will change my rating in the future once it's done. Thank you.
