Is your feature request related to a problem? Please describe.
Hi. Currently, when I left click on History button, it opens a new tab.

Describe the solution you'd like
Ideally I would like an option to prevent history page from opening in a new tab. But if anyone can suggest a workaround that will work for Firefox on Linux and Android, I will be grateful.

Describe the use-case and give concrete real-world examples
Whenever I click on history button, it opens diff viewer in a new tab, so that after I'm done reviewing the changes, I have to close this tab. It would be more convenient if it opened in the same tab, so I could simply use the back button or click on the top title bar to return to the main page without having to close a new tab every time.

Additional context
I can reproduce this behavior in Firefox and Chromium on linux, as well as Firefox on Android.

Yeah, actually there was a lot of people who argued that it SHOULD open in a new tab :) quite some time ago

so a UI options tab would be handy

I've added an option to disable opening the diff page in a new tab. I did some tests and it seems to work as expected. It's enabled by default to keep the current behavior.
Would it be okay if I open a PR?

Or should I create a separate tab for such UI options, like you initially suggested?
Because I would also like to add an option to open screenshot view by default instead of text view (in case Playwright/WebDriver is enabled).
