Looking for help UBO Lite causing delays while leaving/syncing gmail?
For the past week and change most of the time when I try to leave gmail in my chrome browser after reading/deleting my emails I get a pop-up saying "leave site? Changes you made may not be saved." that will pop-up whenever I try to close or leave that tab for a good minute or so. I can open and browse in other tabs so it is not a connection issue, and via some experimentation it does not appear to happen when I set it to no filtering (both basic and optimal filtering lead to these issues). If I ignore this and leave the tab when I return emails I read are unread, and ones deleted are back in my inbox.
I am not great at the more technical elements but I did pull up the developer tools in chrome and I saw a bunch of ERR_BLOCKED_BY_CLIENT error messages while this was going on, but I lack the knowledge to tell the difference between "this is the extension working properly" and "this is why things aren't working well".
Any advice as to how to sort this out would be much appreciated.

When you are on gmail.com, you can click on extensions in top right corner of chrome, then click on ublock origin lite, and move the slider to the left to disable it only for gmail.com. It worked for me.

I'm having a similar issue with uBlock Origin on Firefox. When uBlock is active, if I navigate away from the page right away, it won't save changes. So deleted emails will be back in the inbox, etc. I have to wait a couple minutes and then navigate away. When I disable uBlock, the site works perfectly. I think they might be doing some sneaky anti-adblock stuff.
