Hi Frederik,

A few things:

The configuration file shows 2 antivirus templates enabled: (you stated yo don't have an AV installed, so these are probably old and need to be removed)
KnownConflicts=avast
Template=Avast_Antivirus
--> If you don't have an antivirus installed, please remove them by going to Configure --> Software compatibility - uncheck them. If you see any other templates for things you don't use, feel free to remove them as well (review Lingoes, 7zip, Babylon).

Now the next step is to determine if the issue is Firefox related or not. So please test running other applications (not Firefox) in the Sandbox and see if you can reproduce the problem.
If you confirm that is only Firefox causing issues, you may want to ensure Firefox is up-to-date outside the Sandbox (along with all its extensions). And also test running a new Firefox profile without any extensions to see if that changes the behavior. This can help ruling out a program-based issue, or an extension related one. Please perform the tests in a new Sandbox with default settings (this will also save time and help us determine if your Sandbox is corrupted and causing issues). 

From the screenshots and gif I would recommend that you check your drivers are up to date (with whatever latest version is available for your hardware).

Last but not least, I recommend to fully remove and reinstall Sandboxie [Make a backup of the configuration so you can paste it back later]. I read on your previous posts that you have tried different versions. However, it still looks like you have an old Sandboxie configuration file. You may want to consider using the Beta installer to fully remove Sandboxie AND the configuration file, reboot and reinstall a clean version, then test to see how things work when everything is "fresh" .

Looking forward to the results.

Regards,

Thank you. I will do some steps.

Feedback:

I made the following:

1) I have fully removed and reinstalled Sandboxie with a blank new configuration, which I configured new.

2) I changed the screen from 125% to 100%.

Result: I did not have any futher issue now.



As the issue was solved now, I later did the following (I want to use the 125% Screen):

I changed back screen from 100% to 125%. I did not change any other thing.

-> Now I have again this issue. Please note: This occurs not after some minuts of using firefox in Sandboxie. It occurs after some hours.

Firefox must have full-screen-mode, otherwise the yellowish firefox is not visible. (Yes, if the issue occurs I can change to firefox into normal mode, then I can go back into full-screen mode and the yellowish keeps away. But this is useless, because Sandboxie Control does not react now.

(In windows 7 I have installed all security updates, but not other updates.)

Hi Frederik,

Update, I left FF in full screen (sandboxed) running overnight and experienced no issues. 

-Thank you for the update. I'll see if I can repro and let you know the results.-

Did you test if other applications behave the same way?

Did you create a new profile in FF to see if that helped? (especially interested in knowing if the problem occurs without the extensions)

Are you running any specific sites when the issue occurs? I am not sure how time can affect the behavior, but  I'll give it a go and let you know what I find out! 

Regards,

Hello,

In the meantime I have tested the same with Opera. I have not used Opera until now. So this was a fresh install. Sure I have changed a few settings in Opera for better using it. And I use the following Addon with Opera: uBlock Origin.

In addition:
I use still the Screen dpi setting 125% as shown above.

My windows has all security updates, but
-no other windows- updates and
-I never updated "Internetexplorer". So my system has IE 8. (I will not update it, because only when I do not update it, I can fully deactivate antialysing on my system, and I like a pin sharp font. (I only have a monitor with 1280 x 1024 pix, not 4K)

The issue has not occured after a few hours, but after about two days. During this two days I have set my computer several times into hibernate. And restarted it from hibernate. (RAM is written to the hard disc).

I am looking forward for a solution. Thank you.

While I was using Opera during the 2 days, there were the following error messages:

I don't know if they have anything to do with the issue.

Hi Frederik,

Are you running any specific sites when the issue occurs? . If you provide exact repro steps, I'll give it another go.

If you leave the browser outside Sandboxie for 2 days, do you see the same behavior?

Regarding the messages, they are "likely" related to an extension or an antivirus.

www.sandboxie.com/SBIE2327

Please, test a clean browser to see if that makes the sbie messages go away. If not, then provide a list of what else is running when the issue occurs, and if present, consider disabling any 3rd party AV and re-test.

Regards,

Thank you.

No it does not look like there would be any particular site that makes this issue.

Before I test the browser outside, I would like to say, that I use a third party firewall.  

There is another problem with sandboxie. Maybe this is a more easy case. And maybe this has something to do with the other issue:

Whenever I choose menu->help->looking for updates->check now

I get the following message: Something like:
"Unable to update. An error occured by trying to connect to the sandboxie website."

-> I have now changed the third party firewall to the windows own firewall. But the message "Unable to update. An error occured by trying to connect to the sandboxie website." still occurs.

Hi Frederik,

Test without a Firewall to see if you can make a connection. You may try using a cellphone hotspot or another network. 
Windows Firewall, typically, doesn't block Sandboxie from accessing the server. But if you have changed the default settings, you'll need to ensure Sbie is whitelisted and allowed to access the internet. 

Please access the activation thread to ensure your connection to the server can be achieved:

Another thing to try is resetting your internet settings ( type inetcpl.cpl --> Go to the Advanced tab, restore advanced settings, re-test. If needed, use the Reset button and re-test). 

Regards,

Thank you.

Relating to "searching if there is an update" I was successful.
I found the solution in your Link
https://community.sophos.com/products/sandboxie/f/sandboxie-forum/112743/solved-activation-failed---fixed-as-of-may-13th---please-provide-feedback

First I tried your tipp:
"resetting your internet settings"

This was not successful. My internetsetting by default is:

But then I activated in addition manually TLS 1.1 and TLS 1.2
(this is not the dafault in my system.  As I wrote above: I use IE 8 (not IE 11).

After this change "searching if there is an update" works.   :-)
