I also used 'New Tab Suspender' and 'Total Suspender' add-ons for a while in an attempt to reduce memory usage, but stopped due to Firefox crashes I assumed were caused by them.
Please tell me I'm missing something and that there's a way to do this in Chrome so I can access the tags on my phone????
I have about 30,000 unsorted bookmarks.
Yes.
Because I need tagging.
Sadly Firefox does (for some peculiar reason) not give acceess to the tags on the mobile browser.
So I navigate by folder hiearchy on mobile; read > professional > development > android > db for instance.
Effectively full-text-search tagging.
Oh. TIL. That's... a bit of an unexpected shortcoming I wasn't aware of. Hmm...
(My Chrome session is big enough that I don't quite have the RAM to play with Firefox, which I was coincidentally last playing with just as the WebExtensions update kicked in and broke my UI setup. Welp.)
I can't relate to that amount of tabs, but do have an upper limit of around 100 at which time I start actively trimming them down (either dismiss as having lost importance, digest or bookmark for later digestion).
My bookmarks steadily grow, but are categorized, tagged and labelled in such a way that I can easily find and digest certain types of urls later on when I feel ready for it. They do grow faster then I can consume them though.
