Couple of days ago I opened the Firefox but I saw it keeps opening all web pages with weird characters, I uninstalled it completely, refresh it on safe mode with no add-ons, I see there is no problem with any other browsers suck as chrome or waterfox and others, this problem is only on Firefox...I removed all cookies and everything but still problem going, I use laptop windows 10 with last updates on it...I tried everything available on web sites but no work...I didn't do any changes in about:config...please help me out with this issue, thanks

On Reddit, someone said this worked for them:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste ppdc and pause while the list is filtered

(3) Double-click the browser.tabs.documentchannel.ppdc preference to switch the value from true to false

I don't know what that does.

Do you possibly have disabled multi-process in Firefox by using the MOZ_FORCE_DISABLE_E10S environment variable (its value doesn't matter) ?

  • Control Panel -> System -> Advanced -> Environment variables
  • Bug 1638652 - Content-Encoding not honored when e10s is turned off via browser.tabs.remote.autostart=false or MOZ_FORCE_DISABLE_E10S=1

Please do not modify network.http.accept-encoding prefs on the about:config page as that will cause other issues, so if necessary reset the prefs to the default value if they appear bold.
