Under about:unloads, you will see a list of open tabs, sorted by resource usage. You can click-spam the “Unload” button until that list is empty, or until the most resource-intensive tabs are off the list.

This does not require any third-party dependencies, and the tab will still be present on top. The site will reload once the tab is selected again.

If you have fzf installed, it is easy to integrate it with your bash history. In my .bashrc, I have:

# Introduce fzf-driven functionality as described here: https://wiki.archlinux.org/title/fzf.
source /usr/share/fzf/key-bindings.bash
source /usr/share/fzf/completion.bash

Also, you may be interested in zoxide, which keeps track of paths you have navigated to. Also from my .bashrc:

# Enable an autojump-like 'j' command. Use 'ji M' to select paths starting with M using fzf.
# This needs to always come last.
eval "$(zoxide init --cmd j bash)"

You can use overleaf for sharing only, and write your document locally. I am currently writing my thesis using the git integration, using neovim/vimtex/jabref, and then doing git add/commit/push to sync to Overleaf.
