@jawadalkassim would you mind share in which version of uBlock are you? You can find it under Settings -> Add-ons Manager-> tap on uBlock Origin -> Details - > Scroll to the bottom -> Version
uBlock Version : 1.25.2
We tested on various devices and we are not able to reproduce the issue. Do you mind sharing which sites you are visiting?
I've uninstalled FF and Reinstalled it again then install uBlock Origin and everything is fine.

I was not able to reproduce the issue with uBlock Origin 1.25.0. Now, after I received uBlock Origin 1.25.2, I have exactly the same issue as the issue opener.
OnePlus 7T Pro McLaren Edition / Android 10
Fenix latest build from 4.0 branch (revision 3dc4582fe08e7f8f9c61f0c21b102ab52567bf75)
All websites are affected.
@cadeyrn would you mind to killing the app and open it again?
Killing the app via the Android recent apps screen does _not_ solve the problem.
Try Uninstall uBlock and installing it again.
@cadeyrn
@cadeyrn before uninstalling could you try the "force stop" button on the "App info"?
@cadeyrn this is the button that I mentioned

before uninstalling could you try the "force stop" button on the "App info"?
I tried the "force stop" button, but without success.
Thanks for the reports, we are working on finding the root of the issue, I think so far the workaround will be to uninstall and install again sorry about that.

me too
Looks like disabling and enabling the add-on back is another workaround.
Settings -> Add-ons Manager -> tap on uBlock Origin -> Switch button. Let me know if it works
Yes, uBlock Origin works again after disabling and enabling again. Uninstalling and installing the add-on did not help (I tried this before).
It looks like the issue could be on the GeckoView layer, I opened the below bug to investigate

On my two devices uBO 1.25.2 works fine with the latest nighty-builds.
The only thing I did was to refresh the filter lists on uBO a few days ago.
My devices are:
Huawei P smart 2017 (Android 9.1.0, Stock)
Samsung Galaxy Tab A6 SM-T580 (Android 8.1.0, Stock)
