Forum zhromadźenstwa Firefox

For a few weeks, I've been unable to download Nightly updates via Help>About Nightly because Nightly thinks another instance is updating. I have found no solution or information on this issue. I never run more than one instance, though I usually have 50-60 windows open with many tabs each. Am I hitting a hard coded assumption that more than one instance is running if some number of windows and/or tabs is implying multiple instances? Nothing else seems to make sense so far... This issue just appeared one day; I recall nothing out of the ordinary. Was just trying to download the latest Nightly as I'd done for years and am now stuck with this issue preventing access to updates.

The biggest race meeting of the year, the Cheltenham Festival, is approaching (March 11-14). On oddschecker, used by all racing enthusiasts, when you go to the ante post section and click on Cheltenham Festival which they split up by putting Tuesday, Wednesday, Thursday and Friday and all the races on that day are available. However, when you click on any of the days, all that comes up is the first race. I contacted Oddschecker, thinking that this was there problem. They came back to me saying they could not find a fault and I should try another browser. On trying Google Chrome I found that all the races were available in the Cheltenham Festival Section. It would seem then that the problem is with Firefox. Could you look into this for me or I, and other racing followers are going to have to swap Browsers as information of the races on the 4 most important days of the year (jumps section) is unavailable through Firefox. This has been discussed at length on the forum. Can you try and fix it please as Firefox is my main browser.

How can I ensure my website is mobile-friendly when viewed in Firefox? I’ve been working on my site at Connect Career, and I want to make sure it looks great on mobile devices. Should I use responsive design, and how can I test it on different screen sizes? Are there any tools or tips for optimizing my site for mobile users?
