Step 1. Step 2. And since Firefox 66 it is useless cause Firefox clear the memory automatically as I noticed and that Firefox uses more sub-process which is nice. I Uploaded an images to show which process, now it is using almost 3 GB, and they will not be cleared when finished. I downloaded few more videos, maybe 2 or 3 and not it is 4. You can check the about:memory page for the Firefox memory usage and possible click the button to minimize memory usage.

Usually killing any other Firefox. If you check the image, it uses the least GPU memory. It maybe a process to manage and run add-ons! You should be able to cross-reference the PID with the tool you're using. But it's just a matter of curiosity. Someone may need to debug the extension to understand why it doesn't let Firefox release memory when you close the relevant tab. Maybe I should have mentioned that is problem is new!

I have always used that download helper and it worked just fine. I can't remember, but since Firefox 64 maybe 63 or even 62, or let's say it is a new problem. The problem was not happening before, with the same version of that extension.

If someone is a pro here and reading, it is not about downloadhelper, even when I use "Dark Reader" add-on I notice after a wile it will slow the browser. It is how Firefox manages add-ons, I think Firefox fails to clear memory for add-ons in general,. Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems. You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

I suggest you contact its support as Firefox has gone thru several reversions in the last 8 months. I will return for sure, but I tested downloading lots of files, Firefox used almost 3GB RAM, and when done downloading the memory went done to MB and that was something new!

Not only that, I have even noticed using the dark reader add-on will not slow down the browsing as it used to be! The question who did it?

Thanks so much Mig. I don't know how that would have arisen, i certainly never deleted this folder myself. Anyway thanks! Hey Mig. I verify what you wrote in your proposed solution on two PCs: the configuration of the manifest is identical on the two PCs, both with Ubuntu The bottom line is that in one PC it works perfectly.

In the other one, there no way to make it work. I cross checked the system permission s for execution but they are OK and moreover they are identical in both PCs. Ts Garp. I have he same problem. So I checked for the net. I removed both after that. I have. Elementary OS 5. Mozilla v Video DownloadHelper 7. Eveything else on my laptop works excellent and I have no issues.

Wish I could help, Ts Garp, but I'm no expert. Mig's advice sorted me out. I imagine you have to find the right place for the Coapp stuff, but who knows where.

Good luck! Your Firefox is 64Bit. Copy the file from the ignored to the used folder, then it works. Mac Guy. I have the same issue on catelina with latest version of firefox. Has anyone figured out what's going on on the mac side? Jeff Deischer.

I have Ice Dragon I installed it. I didn't do anything fancy like change the location of anything. I don't know about changing directories. What do I do? Ruediger Port. Thanks so much, Mig!
