Thanks for the considerable effort you put into Session Alive. I know how challenging is coding. However, I've now read several responses from you stating that you don't recommend Session Alive use with banking sites. Ok, say so up front.
The problem I had - before I installed - is that at the top blurb level, it doesn't read '(Not for banking.)', nor does it state that anywhere in "About this extension". So I've wasted my time, but you don't want that, right?
BTW, I suspect this time-out duration issue is more about greed than security, more about the nationwide cost of cloud server seats. Years ago, my credit union default time-out was 10 minutes, but I could option for 40, which was enough for me. Then a national banking services company (was Digital Insight, now Candescent) took over with (originally) free web services forming a near monopoly at CUs. Now 10 has long been the firm limit. Yet my giant credit card bank gives me much longer, 20-30 minutes.
Also BTW, upper middle class users get around this corporate hassle (enforced on local CUs) by paying monthly for money management software that they need daily, which quickly logs in, uploads and downloads the state of multiple banking-financial websites, and quickly logs out.

does not work

Keeps banking.postbank.de alive: Works well.

Didn't work at all. It would be helpful to have some directions beyond the few sentences on the page. It's very possible I'm not setting it up correctly, but after half a day of playing with it I gave up. It made, quite literally, no difference whatsoever.

Very difficult to use

Didn't work, on the one website I needed it for (Chase). Uninstalled. Might try again if I need to use another super annoying short timeout website.

I tried this on Secret Server and the oVirt admin UI, it didn't work on either one. I had the refresh interval set to 1 minute, it still logged me out.

Seems to work perfectly well when used as designed. Suggestion: provide detail on what the server returned when the status was not 200.

I only need this plugin for one particular site, and the plugin keeps saying that no rules are running on the site, even after creating rules using the Add button.

Doesn't work for me, neither in foreground nor background mode

Very usefull. However, it often drops a rule while in execution or sometime not detect a named and loaded page. It needs frequent restart with manual page refresh. Also it seems not working when Windows is suspended.

Great addon! I've been looking for years for this. Thanks!

Honestamente: todos os sites que tinham as sessões encerradas continuaram encerrando as sessões.

Works as promised! Very useful :))

Works very well~

Works well with an app that constantly signs out users every 30 mins. Adding a rule to refresh to home page every 28 mins works well.
