too many processes for a single tab in firefox (ubuntu 18.04)
Opened a single tab in Firefox and checked the CPU resources used. There are 40+ processes created by Firefox. Could someone please explain why these many processes are required? currently using ubuntu 18.04 and firefox version: 61.0.1 64 bit

Thanks for the screenshot.
That's bizarre. There should only be one content process with
per instance of Firefox.
Is there some other info required which can help in debugging the issue. I really do not want to reinstall Firefox again.
Hi, Firefox 62.0 is released now. If want to work with a even number : Pick your language or back URL up to 32 bit : https://archive.mozilla.org/pub/firefox/releases/62.0/linux-x86_64/
I have no idea if any of this applies to you (Windows person & bold)
To be Checked and turned off unless needed for accessibility : Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.
Multi-Processor Support : Go to the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please. Note : Hardware Acceleration is for Video Card, Monitor to see if remain off or to turn back on.
Only Disable as last resort.
Multi-processor Can completely disable it this way in about:config : dom.ipc.processCount set to 1 browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false
Only move to esr if low ram and old system.
Firefox Extended Release Version : Firefox ESR does not come with the latest features but it has the latest security and stability fixes.
If do please :
I would also suggest a Malware scan, yes I know... but do so as your not invulnerable as you think you are.
I do not know why a comment was made with out a suggestion by jscher2000 as is not like him to do that.
Please also try : SAFE MODE
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (file: localstore-safe.rdf)
- hardware acceleration is disabled (Options > Performance > Uncheck to view)
- plugins are not affected
- preferences are not affected
TEST''''is issue still there ?
Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.
You can find the full version of the current Firefox release (62.0) in all languages and all operating systems here:
