Slow Firefox startup after Windows Startup with lots of tabs open

dd — Sat, 05 Oct 2024 14:14:25 GMT

Q: When I put my Windows PC in Hibernate mode with Firefox open with lots of tabs (10-12+), on wakeup when I click on any tab it takes ages to get the page (>5 mins). I used Resource Monitor to find out it is accessing files in my storage/default folder of my profile.

Does anyone else have this happen to them?

What is the best way to reduce this wait?

It also happens when I close Firefox while tabs are open and shut down the computer. Again, on FF startup all tabs are remembered and try to open but are super slow. Of course, this doesn't happen if I close all tabs and then Firefox and start opening new tabs on startup but I just like the convenience of having my favourite tabs already open.

Any help would be appreciated

Thanks
DD

I'm not sure about at startup, but this happens to me when I hit the update link (green circle) at the top. Firefox updates, all the tabs pop up (about 16 in two different instances/windows), then they take several minutes to load. Here's what Task Manager shows:

It's thrashing the hard drive and doing nothing on the network. It appears that FF is disk-bound. What is it doing? I don't want a load from disk cache, I want it to hit the network and refresh all the pages on the tabs! Maybe it's my computer. How do I determine what's happening here?

Yup. The screenshot below from Resource Monitor is a short version of what I see when I startup FF and click on an open tab. It is usually 3 or 4 pages long and shows that it is reading objects with site names that I haven't even gone to in months(?). This is why I assume it is a cache update problem/issue.
For now, I am going to move my FF profile folder to an old SSD from its current residence on an HDD. Initially moved it off my main SSD to reduce disk thrashing on the disk to help it extend its life.

Going to request a feature to have the option to ask for reload from the website rather than the cache upon startup. Maybe that will stir up the developers to give us feed back on this issue.
