'''Firefox reloading the tab issue''' To reproduce the issue: # Open Firefox on Android Device. # Open any web-page on a new tab. # Open another Tab and switch to it. # Switch back to the first tab you opened in Step 2. The web-page opened in Step 2 gets reloaded. Also # Open Firefox on Android Device. # Open any web-page on a new tab. # Switch to any other App (two seconds is enough) # Switch back to Firefox. The web-page which opened in Step 2 gets reloaded. '''Desktop Site Issue''' On turning-on the 'Desktop site' on a particular Tab and switching to other Tabs or to another App, coming back to the original Tab reloads the page as I mentioned above and turns-off the 'Desktop site' i.e. the Mobile site is shown while the Firefox Options Menu shows the 'Desktop site' still turned-on (via toggle button). '''Use-case''' Logging into my bank website via Firefox, I enter my details and wait for One-Time-Password to arrive as SMS or Email. I now switch from Firefox to the SMS App or Email App to read that One-Time-Password. I switch back to the website on Firefox to enter that One-Time-Password. Now, as soon as I switch back to Firefox, instead of retaining the web-page, it reloads it. I have to once again go through the procedure of entering my details and switching the app to read the One-Time-Password and then coming back to Firefox to see the web-page is reloading again and this continues on loop because ''Firefox is unable to retain its web-pages and reloads them as soon as one switches to another Tab or another App''. I have Samsung Galaxy S8 with 1.1GB RAM available all the time and all Battery Optimisations such as not allowing to run Firefox in the background or putting it to sleep is Off.
