  1. Pale Moon still works on Win7-64bit, as of October 12, 2023. They were having some memory leak issues that were causing crashes, but the latest update seems to have addressed it.

    Opera…it works on Win7-64b as well, but its architecture is abyssmal unless you have over 4Gb RAM. Not many older PCs have that. So it can get bogged down pretty quickly.

    Firefox is as bloated with garbage as it could possibly be, and has adopted all of the modern security risks presented by Chrome just so it can “keep up” with market share. It too has a massive RAM requirement to run decently. No longer a viable option for me, though like Opera it does technically work.
