Really? When I first met Sun machines they were selling 68k-based Sun machines that were better specced than Apple and Amiga and such but left them dependent on Motorola’s architecture that had indirect address and thus no future.
Sure they had an in house chip development ARM team right at the time when RISC economics looked good but CPU architecture had to work harder and harder to beat the memory wall and SPARC was not competitive by 2005 and “Hail Mary” projects like CoolThreads were difficult and expensive but did not deliver for customers.
Hypothetically customers could benefit from that proprietary stuff but they benefit even more from rapid progress is competitive, commodity markets.
When I was working at the library circa 2005 we were thinking about replacing all the Windows computers that patrons used to access the online catalog (and other services) with a web browser with Sun Rays, we probably would have bought a few hundred of them and we would have bought some SPARC servers to back them up.
We could have gotten Netscape to run under Solaris but after a week of effort I wasn't able to get Mozilla to build, so no modern web browser. So no Sun Rays. No servers. DTrace and ZFS were great innovations but without the magic of "can run the software you need to run" they are just Blub. Had Sun done the work to get Mozilla running on their machines and forgotten about DTrace and ZFS people might still be using Solaris... but instead DTrace and ZFS found an audience by supporting... the commodity OS!
(arguably at that time supporting a web browser was the #1, #2 and all the way through #99 task that the Solaris team should have been working on at that time and everything else from Java to Tcl to ZFS was a dangerous distraction... and that's how companies in a position like Sun die)
You must be misremembering something. Netscape/Mozilla/Firefox had always tier one support on Solaris. You had nothing to build, just download and run, with perfect compatibility.
I only ever ran Netscape/Mozilla/Firefox browser (and still today in 2026). My desktops and servers were all Solaris from mid-90s to 2012 or so. Never a hiccup running the Netscape family browsers (and servers too).
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.
"When I was working at the library circa 2005 we were thinking about replacing all the Windows computers that patrons used to access the online catalog (and other services)"
why were you thinking of going Sun, as late as 2005? just easier to lock down, like kiosks?
We already had a big investment with Sun for back end systems like the library catalog. We perceived managing a big fleet of desktops as a hassle, it was worse then it is now.
