script tag inserted in my page
Firefox (97.0.1) inserts a script tag into my page
<script type="text/javascript" src="/052D8F33-74DD-5940-B13A-6A6B9ED5FFB2/main.js" nonce="C7F6111EAF568746B15137E4E92C6C3E" charset="UTF-8"></script>
This seems to be something from Kaspersky labs:
(function(){ var KasperskyLab = {SIGNATURE:"8413313B-34AF-E24F-BC0F-C01964DF03AD"
Why is this appearing in my page when browsed with FF? What can I do to eliminate insertion of undedirable code into my pages?

Do you have any add-on installed by Kaspersky? Check about:addons and about:third-party.
No, I have no add-on installed at all.
Do you use a Kaspersky product on your device?
What is the address of the website that you are trying to view?
The use of a relative URL for the script src suggests that the script is installed on the website you are visiting. Does it seem that way to you?
Do you see the same in other browsers on the same device and on other devices connecting through other networks?
I have no Kaspersky products installed on my device. Other browsers (Vivaldi, Opera) do not show this behavior. The page is served by apache httpd running on my machine (accessed by localhost). It is a hand-written html page.
When you viewed the source of the script, did it load from your locally installed web server or does the address redirect somewhere else?
Could you disable any proxy:
- Windows: "3-bar" menu button (or Tools menu) > Settings (previously "Options")
- Mac: "3-bar" menu button (or Firefox menu) > Preferences
- Linux: "3-bar" menu button (or Edit menu) > Preferences
- Any system: type or paste about:preferences into the address bar and press Enter/Return to load it
In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.
Set "No proxy" and click OK to save the change.
Any difference if you reload the page bypassing the cache (Ctrl+Shift+R)?
