I was in the process of writing a somewhat lengthy response and went to another webpage or webpages and when I went back to the webpage where I was writing the somewhat lengthy response, the webpage was completely blank! The Back and Forward buttons were grayed out, Refreshing the webpage did nothing so there was NO way to get the webpage back. Interestingly, when I hover over the URL, at the end of the URL for the webpage, it had "about:blank." Things like this are very frustrating and waste a lot of my time. In addition, another problem I reported on 3/20/25 (link is: [https://support.mozilla.org/en-US/questions/1500741 A webpage I just closed recently is not listed Back arrow issue]) has still no response. Also another frustrating thing about the Firefox browser is that at times the Bookmarks sidebar disappears. I need a reliable browser, not one that sort of works! I request that these issues be addressed soon.
