If you do open too many tabs in your browser these tabs may eat lot of system resources where Mozilla is trying optimize their Firefox browser for speed with Memshrink project, we’ve covered two extensions one, Dormancy which unloads all tabs that haven’t used by you for a while and second, CleanupTabs which automatically closes unused tabs. Most of the users prefer first one over the second, UnloadTab is yet another Firefox extension similar to Dormancy unloads inactive tabs to save memory.
After installing this extension, UnloadTab treats tabs as inactive if they’re idle for 10 minutes (which you can change from extension options) and inactive tabs will be dimmed to let the user know. Any tab will be restored to original state when you click on that tab on tab bar.
User is allowed to exclude some sites on tabs to be always loaded by adding their web addresses one by one manually in “keep address loaded” field of options. Pinned tabs are pre-selected to always loaded.
From any tab context menu you can unload that tab, other tabs as well and you can always keep address loaded for the selected tab.
Since the time you posted this, UnloadTab has been removed, and Dormancy is described as experimental.
Have any of these features made it into Firefox? Are there any similar addons?
I use IMDb a lot, and if I open 16-20 or so IMDb pages one right after the other, on new tabs, Firefox is almost guaranteed to max out my memory and crash, even if I never actually view most of the tabs. Or if I visit pages with a lot of images on them, like a blog with travel photos, the same thing can happen on just a single (long) page. I have very little spare hard disk space either, so virtual memory cannot be increased.
It’s disturbing that approaching 2013, I still have a browser that can be crashed on a single page, or just by opening several tabs and not even viewing them. I’m cretain that neither of these actions caused the least trouble on Firefox 3.6, back when I had only half the RAM on my PC.
Try Bartab here https://addons.mozilla.org/en-us/firefox/addon/bartab-lite/. And why don’t you have look at Suspend background tabs extension also, i hope you like it, here is the link https://techdows.com/2012/05/suspend-firefox-background-tabs.html
Thank you for sharing this post about these extensions.
