Firefox containers, paired with Simple Tab Groups helped me to fix this. I work on multiple projects and it's common to have multiple Github and alike issues, and other pages open. With Simple Tab Groups, you can select to group and only show tabs that belong to just one group. It's easy to move tabs between groups. When the tab group is switched, tabs from the other group are offloaded from memory, effectively making them bookmarks. Pinned tabs (webmail client, a note taking app, and music player in my case) are shown in all tab groups. I know it helped a lot, because I use Chrome on my Android, and I always have ":D" in my tab button because I have more than 100 tabs open.
