Hi, this question, or complaint, is addressed to the devs. I must to express in beforehand, that firefox is my preferred browser, but i hate to update it, because after every update, the program gets deteriorated instead to improve. This time I have an issue that never happened me before. I use since a long time, the multiprofile feature without any issue. Practically for that feature, is why i prefer this browser over any other But after the latest update (131.0.3 version) i cannot open any of those profiles and the program shows me this warning "your firefox profile cannot be loaded. it may be missing or inaccessible profiles". The possible cause resides because I store the profiles outside C: partition. I have C: and D: partitions on my disk, and I store them in D: partition because it has more free space. So I know perfectly the location of the profile folders and they still exist of course. Besides, i have another pc with the same specs, and happened the same. I experimented, and I could see that the new firefox, cannot detect the old profile folders' path when you select them at firefox's profile manager. The fact is, that if i copy one of the profiles to the default profile folder, firefox can perfectly recognize it and open it. Also if i create a new profile inside the custom profile folder (which as I said, is outside C: partition) it also can open it. So i don't know why it can't open the other old profiles. So, copying all the old profiles to the default profile folder IS NOT an option. NEITHER recreating all those profile folders. Remember, firefox was working fine, until the latest update, so please fix that or tell me please how to override that issue. Thanks for your attention
