Fóram Tacaíochta Firefox

I have a number of pinned tabs, which occupy a lot of space.

I'm looking for something like a drop down menu to the left of the tab bar for only pinned tabs, which would then eliminate there display on the tab bar. Kinda like a pinned tab bookmark button.

I'd prefer it on the tab bar, but I guess a toolbar button would do.

I have noticed few problems using history with Back and Forward Button.

Firstly whenver we use back button my website to the hiistorical visited website in that same tab. However i have noticed that it keeps forgetting the count or number of historical sites visited in the same tab.

For Eg: if i navigate to several pages on the same site. Firefox will only remember few clicks upto 2-3 back.

Surprisingly when i click back button i am not able to come back to the last visited page by clicking forward button. Once i click back button then i wont be able to come to forward sites as the forward pages are fully lost.

I dont know why is this happening

I want my search engine to show on new tabs instead of using the address bar (a very inefficient way to do a search, frankly). For now I either have to use firefox or click on my search bar in the header to get it to come up.

when playing a video on youtube a mute button should appear when hovering over the tab when language is hebrew, this sign appears always, being on top of the website icon

I use two monitors, and I have multiple firefox windows open at once. When I turn on my pc and open firefox, the windows almost randomly position themselves on both monitors, sometimes they are not maximised either. How can I change this behavior so that all my firefox windows open, maximised, on one monitor rather than both?
