There was Netscape support, but then there was that crisis when it seemed that IE would be the only viable web browser, the realization that the Netscape was too FUBAR to build on, and then Mozilla got rebranded as Firefox.
They probably had an official Solaris build of Mozilla later on but if one had been available at that point in time I would have installed it on the SPARC machine I had under my desk. The ship had sailed in terms of the organization's capital planning.
If you were happy running Netscape later than I was you might have felt supported.
This sounds right. There was a "dark ages" in the early 2000's, where Unix/Linux browser support was terrible. You were either stuck with old Netscape 4.x, which crashed every half hour, or you had to work with half baked, almost unusable beta builds of Mozilla (pre-Firefox). Because of this, I actually ran Windows on my desktop for a while!
There was never a time when Netscape Navigator, Mozilla or Firefox were not fully supported on Solaris (earlier, also SunOS).
When Netscape Navigator first came out eary/mid-90s I ran it on SunOS while working at a Sun shop, it always worked perfectly.
By the time the Netscape browser was open sourced in 1998 I was working at Sun and running it on Solaris, always worked perfectly. I attended the open sourcing party Netscape held in San Francisco, still have the autographed CD with the very first open source release source code. Netscape paid for buses from Silicon Valley to SF for people to attend the party. Fun times!!
In 1999 the Sun|Netscape alliance happened, AOL took the consumer software part including the browser and Sun continued the server product development under iPlanet brand. For a while I worked in the Netscape campus that year, and I continued working on iPlanet servers for years after that. Since the browser code had been open sourced, development continued outside AOL becoming Mozilla and later Firefox. Always first class on Solaris.
Firefox branding happened much later (wikipedia says 2004). Still working perfectly on Solaris. Only browser I ever ran, always on Solaris, until the bitter end (oracle lawnmower in 2010).
So yes I can confidently say it always ran perfectly on Solaris (SunOS in early years), having been there through all this and have fond memories of it all.
